Unless I'm missing a trick I can't seem delete and apply to a range with the delete assembly function.
I think that instead of delete subassembly we should have a turn on/off fuction button for each subassembly in the edit dialogue.
This way you could apply subbasemblies to not display over a range and turn them on or off acordingly in the same dialogue.
Presently after deleting.modifying a subassemblies parameters you can only delete the modification in the corridor dialogue not in the edit section dialogue.
PS there seems that there may be a bug with the delete all overrides (corridor dialogue), when I use it and exit the dialogue the overrides still exist. You have to delete each, one at a time.
