The "Save Bodies" functionality needs to be revamped. First you need a better way for naming conventions. So if you have 60 bodies and did not name them in the feature tree you have the ability to functionally name all of them. Such as you want to give 10 of them the "Core INS" name with a instance number. Then name the next 10 "Cavity INS" with instance number.

Also it gives you an ability to create an assembly file and place it wherever you want but the individual part files do not follow the assembly location. If you pick a folder for the assembly place the part there also.
