I think you need to split this to more complex approach, id est:
- register the first one as with the current name
- use indexed variant for the rest

It will give something like %s-trigger, %s-trigger1 (if start from 0),
and so on. This way you won't break user space when it was defined for
a single trigger.

(Yes, I have read all emails in this thread as of time of replying to it.)
