Some products come with their parameter groups a mess. Some have many empty groups and morphs unnecessarily buried many levels deep. Some parameters are grouped in an illogical, disordered manner (such as some standard FBMs in "Other".

Some vendors are conscientious about uncluttering their products before releasing them, others aren't.  I'm sort of compulsive about not having messy parameter structures.

Is there a quicker way to clean them up without going through each body part and repeating the process of rearranging / deleting parameter groups? Is there a script or something that makes this less tedious?
