Help Send IM from contacts through a different app

[Th3sandm4n]

I just got my Moment and I'm loving it (first nice phone).

I do have a quick question though:
Is there a way to change the default app that is used to change which IM client is used when clicking the the "Chat using X" in the Contact info? I would really like it if it would open up with Nimbuzz instead of the stock one. (this would be ideal also since it supports the skype stuff as well)

Or maybe does anyone know of maybe a decent contact managing app that does this (a bunch of them that look decent are pay) since I don't see it described specifically in any ive researched.

If it's not possible yet, that would be good to know also
