+array describes to the other canvases which caused this conflict. When a shareable object is exported and then imported into a new space,

+This result indicates that the copy was successful for the `marketing` space, but it was not successful for the `sales` space because the
+index pattern, visualization, and dashboard each resulted in a conflict error:
+
+* An index pattern with the same ID already exists, so this resulted in a conflict error. This can be resolved by overwriting the existing
+object, or skipping this object entirely.
+
+* A visualization with a different ID but the same "origin" already exists, so this resulted in a conflict error as well. The
+`destinationId` field contains the `id` of the other visualization which caused this conflict. This behavior was added to ensure that new
+objects which can be shared between spaces behave in a similar way as legacy non-shareable objects. When a shareable object is copied into a
+new space, it retains its origin so that its conflicts will be encountered as expected. This can be resolved by overwriting the specified
+destination object, or skipping this object entirely.
+
+* Two canvases with different IDs but the same "origin" already exist, so this resulted in an ambiguous conflict error. The `destinations`
+array describes to the other canvases which caused this conflict. When a shareable object is copied into a new space, and is _then_ shared
+to another space where an object of the same origin exists, this situation may occur. This can be resolved by picking one of the destination
+objects to overwrite, or skipping this object entirely.
+
+These errors need to be addressed using the <<spaces-api-resolve-copy-saved-objects-conflicts-example-1,Resolve copy conflicts API>>.

+ * This function takes all objects to import, and checks "multi-namespace" types for potential conflicts. An object with a multi-namespace
+ * type may include an `originId` field, which means that it should conflict with other objects that originate from the same source.
+ * Expected behavior of importing saved objects (single-namespace or multi-namespace):
+ *  1. The object 'foo' is exported from space A and imported to space B -- a new object 'bar' is created.
+ *  2. Then, the object 'bar' is exported from space B and imported to space C -- a new object 'baz' is created.
+ *  3. Then, the object 'baz' is exported from space C to space A -- the object conflicts with 'foo', which must be overwritten to continue.
+ * This behavior originated with "single-namespace" types, and this function was added to ensure importing objects of multi-namespace types
+ * will behave in the same way.
+ *
+ * To achieve this behavior for multi-namespace types, a search request is made for each object to determine if any objects of this type
+ * that match this object's `originId` or `id` exist in the specified namespace:
+ *  - If this is a `Right` result; return the import object and allow `createSavedObjects` to handle the conflict (if any).
+ *  - If this is a `Left` "partial match" result:
+ *     A. If there is a single source and destination match, add the destination to the importIdMap and return the import object, which
+ *        will allow `createSavedObjects` to modify the ID before creating the object (thus ensuring a conflict during).
+ *     B. Otherwise, this is an "ambiguous conflict" result; return an error.
