API return Id on post_document

[pintariching]

Would it be possible to return the Id of the created document when sending a POST request to documents/post_document/?

Right now, I don't think I can insert a document from an external app and somehow reference that new document in my external app without having the user manually select the document,

One workaround I've been thinking of is that I could make a tag, with a random name, assign the document that tag, save the document, and then query the API with that tag, to get back the document Id, but that seems like a very roundabout way to do it.
