Allow duplicate items

Prerequisites

• I have read the documentation;
• In the case of a bug report, I understand that providing a SSCCE example is tremendously useful to the maintainers.

Description

I see that we can add new items in two ways using ArrayFields, either adding a new item at the bottom of the list, using onAddClick, or adding a new item on a specific index, using onAddIndexClick.

These are really nice features, but it adds an empty item, or, pre-populated with the default values set in the schema.

What I need is to be able to duplicate an item, and, I'm curious if maybe there's a duplicate item functionality, or, maybe it is possible to add a new item with pre-set values?

Thank you!

You couldn't do that with onAddClick, but you could instead store the form data in the component's state, then use setState to change the form data.

@epicfaace Sorry for the extra question, after creating a custom ArrayField component in the props I see formData with my actual data information and empty formContext. How can I update the state for re-render form?
