Profilemanager multi association to profile

[d.davolio at mastertraining.it]

Hi,
sorry to disturb. I bet other people asked the same question but I can't 
find an answer:
is there a way to associate the desired groups to a profile, outside the 
GUI?
I'm asking because the gui permit only one-to-one association and I have 
+1000 users and +100 groups, so doing the association by hand is time 
consuming, so to speak :)

Thanks for any info!
