Detach to separate symbol?

[m.vlad 36]

I've just gotten into using Affinity for responsive UI designs. It's quite great! (when it's not doing the constraint group bug that moves the contents somewhere else entirely or when it breaks Symbols if your top level layers in that symbols have constraints added).

What I have found out, however, is that many times I'd like to make an iterative symbol, just for a select group of symbols to have some elements missing and some stuff placed somewhere else. While one could delete all but one object of that query and do the modifications in that one then duplicate that one, it's cumbersome and is quite difficult with large batches of objects (and it'd also need to be repeated for any other major changes in that object).

Thus I request having a Detach to separate symbol feature (that can work on multiple copies of the same symbol selected).
