Hmmm I've thought about that before. It'd be a little bit of trouble for me to implement but I guess not too much effort.
I've thought this could be circumvented by making a blueprint via mod, then removing one side with a destruction planner (after placing it), then creating a new blueprint from the newly placed ghost items.
So I don't know if this feature would be in high demand. Do you think I should still implement it?
Edit: Will attempt to implement it the next few days! Thanks for the feedback
Edit2: Implemented for next version
