It would be nice to be able to create a selection set for the Purge Unused dialogue so that users could include/omit standard selections instead of having all unused items selected by default.
It could function similar to the print dialogue, allowing me to single out commonly purged items without having to manually pick through them each time. I commonly find myself purging only a few categories, but wanting to maintain the majority of components within a project.
This would allow users to quickly purge out any unneeded model elements, without accidentally removing needed annotation items- making the model more lightweight for the documentation phase.
