Reuse existing field in multiple Group fields

[Tim-Wils]

What are you trying to do?

It would be great to see Group fields and existing fields work together like so:
If I create a form with 2 groups Delivery Address and Invoice Address I want to be able to use an existing Address Component Field (from a stencil or a separate components form) to use in both groups.

This way you can create a Stencil or Form with reusable sets of fields and add them in a synced way via Groups.

The names of the fields should then always be namespaced or prefixed with the wrapping group-handle like so:
deliveryaddress.addresscomponent.street
invoiceaddress.addresscomponent.street

What's your proposed solution?

Make Group fields be able to use existing fields as a wrapper.
