Specific Secondary Nav for Pages/Categories

Hi there,

my first question here, so far its the smoothest and most adjustable piece of wordpress theme goodness i ever used but this time i got stuck.

problem/question: is it possible, to have a secondary navigation with a specific menu listed for a category?

example: i have 5 posts belonging to the category1, all these 5 posts should have their own secondary nav with a specific secondary nav menu, same goes for category2 to have a different secondary nav as category1 and so on. the primary nav would always stay the same and would give always the same options, no matter what category is chosen.

I hope that is kind of understandable what i try to do, if there is somebody with a hint to the solution let me know, thanks :)

greetings
