"triggering" a group of triggers.

Let's say I have a bunch of triggers setup in a group that basically keep my character buffed up. Is there a way I can make an alias to fire off every trigger I have in the group and make it so each time I add a new spell it keeps it updated?

Yes, dozens of ways. The basic trick to all of them is that you don't run the triggers. You make the triggers execute either a script function or an alias, and then you activate that.
