Muliple Rank Sets

[xg3]

I'm looking for a hack that allows you to make multiple rank sets.

For a simple example, a user can choose..."Plant" or "Animal" category.

The rank images (stars or whatever) will correspond to whichever category he picked. For example, if a plant user has 10 posts, it will show a maple leaf, but a 10 post animal user will show a cat or something.

So different images corresponding to different categories at the same post counts.

It would be easy for the admin modify rank page..
10 posts: ____________ (url for plant category) ____________ (url for animal)
50 posts: ____________ (url for plant category) ____________ (url for animal)
