Gendered Rank Question

[Crystal Shards]

I was wondering if there was a way to make ranks gendered in vBulletin. That is to say, if someone lists "female" as her gender identification, she get to go through particular ranks as she posts, and different ranks will show if a person identifies as "male." So for example:

If male:
100 posts: A
200 posts: B
300 posts: C

If female:
100 posts: D
200 posts: E
300 posts: F

I hope that makes sense.

EDIT: I would also be open to the possibility of having usergroups that did this, now that I think about it.
