It would be awesome if we could group a selection of models so that if we select 1 it selects the whole group. This would be useful for people who make detailed models from multiple models that will be repeated in the entire build.
Please, this. Detailed models are a huge headache without this feature.
EDIT: I actually just figured out a sort or workaround for this. I took my model I wanted to be grouped, exported it as a 3D model with the pieces merged, then added it to a custom collection. Not the most elegant solution, and there's no way to UN-group them, but it works for what I'm trying to do.
