Hi Red, I think this would be a useful feature for everyone 
Being able to make blueprints is great, but it would be even better if when creating said blueprint there was a checkbox to group objects. That way when it comes to remove the blueprint by hitting it with a pickaxe (for example) the whole blueprint is destroyed, as opposed to the current setup, where you have to destroy each individual component that makes up the object.
For example, I've made my own sconce, after a while I decide I don't like it's location, maybe I want it a little higher/lower (long after undo command has expired). Currently I have to remove each object component one-by-one.
Can we maybe please get this feature in the future
