Maybe I am using LODs (Level of Detail) different than designed, but I would like to be able to promote a level of detail to Master.
What this would do is allow you to essentially brainstorm in an assembly, and then once you have your model the way you want it, you could promote your custom LOD to Master, and it would then delete all unnecessary constraints (those that are suppressed in the custom LOD), make overriden dimensions current, and unnecessary parts (all suppressed parts).
It would really be a nice way to finalize an assembly.
Maybe there are some required options in the process, like retain suppressed content center parts, retain/delete LODs of children subassemblies...
