We have different clinical trials that have their own requirements and we'd like to be able to have each trial have its own user manual. Trial 1 might use modules A, B, and C, while Trial 2 uses module A, B, D, E, and F.

Right now we have a generic user manual, so all trials get the same manual. I see that Intercom allows up to 30 help centers - we’re expecting to have more than 100 trials (and thus help centers) shortly. 

I cannot do this through Intercom's user attributes since the same user (say, a Doctor) could work on both Trial 1 and Trial 2 and would need to see different UM content based on which trial they are working on at the moment.

Any suggestions?
