Is there a way to add multiple extra field groups to a category?

Maybe an extension or something? Cause right now Im only able to add one extra field group on a category.

this www.jiliko.net/extensions/k2-sherpa.html extension would allow it
I dont think its 2.5 ready at this point.
by deafult k2 does not support this

Nice! Thank you very much :) I will try it out.

No... I only works with joomla version up till 1.5, and since im using 1.7, then it won't work for me...

So, anyone got another suggestion? :)
