Very often I use 'Create Model Set from Selection' and need to go back to the original model set and delete the part. This is because I like to break out my assemblies into smaller sub-assemblies for flexibility. It would be nice to have an option that created a model set from your selection and automatically moved the selected items to the new model set, instead of copying them. It is a bit tedious creating a lot of model sets from a base assembly and having to go back to the base assembly and deleting those parts out, especially with a large scene tree. It would also be nice to have the option to move things from one set to another, rather than only being able to copy it.
