Didn`t we have a Option to merge Building Groups into one?

Wasn`t there a Option to merge those? Not in the Mood to remove everything from the Groups and select everything.
Only have the Option to save it as a Blueprint or remove everything from the Groups
Is this a Bug or am I remembering it wrong?

You cant merge groups if both groups have grid pieces in them

Ok, good to know. Wanted to see what it looks like if I replace the Walls with those other Glass Panels anyways
