Lock model in place or designate no print areas during 'layout all'


So this night be a bit of a niche thing, but I’d like to lock out parts of the build plate to prevent models from printing there, it’s a small area in the center, if I can lock it out, then I can keep using the rest of the build plate without accidentally putting a model there and having it turn to mush. So I’d like to either be able to put a dummy object there to lock it out so it won’t put models there. Also having it so all tall models are in a specific area perpendicular to the front so that it doesn’t have to travel as far would be nice.

An alternative to that idea would be to have some sort of a polygon tool to block out parts we don’t want to use, but the ability to lock some models in place and let others position around them would be a lot more useful.
