Example use case:

I create a floor plan card that all my styling & interactions > then convert to symbol > I then create a section on some page using a cms collection that has all my floor plan data > I want to drop this symbol in and connect it

So

request 1: insert symbols into collection

request 2: override it's fields with CMS data

I know I can recreate but I don't want to rebuild or copy/paste classes, objects or whatever. I want seamless insertion after I initially build my symbol.
