Hello! My first post here and very new to scripting.
I’m just wandering if it’s possible to process block instances in the following manner:

BlockInstanceLayer:
BlockInstance001:
Solid001, BlockInstance002
Layer001:
Layer002:
Solid002, BlockInstance002:
Solid003

to

BlockInstanceLayer:
BlockInstance001:
Solid001, BlockInstance002
Layer001:
Layer002:
Solid002, BlockInstance002:
Solid003

So find for each object in each block instance or nested block instance the layer structure it is a child of and recreate that layer structure under the main (top) block instance layer (and have it moved there).
