Remove Tiles under blueprints

[EmuLegs]

I am trying to make a blueprint with some tiles under parts but no tiles under others parts
Could you make it so I can (shift or ctrl) + Right click to remove tiles under Entities please?

Could also allow shit+left click to turn tiles back on under an Entity




PS: I know I can turn the entities off to edit the tiles, but then I can't see the items I want to keep :/
