Improved bodygroup tool?

Has anyone already made an improved body-group tool yet, the only one I’ve seen just has one bodygroup and one subgroup slider bar. What im looking for is a version of the bodygroup tool that will save some time by letting you change multiple subgroups at the same time without having to then switch to a different bodygroup.

for instance

bodygroup 1

<subgroup sliderbar>

bodygroup 2

<subgroup sliderbar>

bodygroup 3

<subgroup sliderbar>

and so on.

also the ability to save pre-set groups would be useful as well so that you could easily switch to a different setting if you had already made a pre-set for a particular ragdoll.

thank you for your time.
