I may be veering off in the wrong direction with this answer, I'm not sure, but it seems like this is a simple case of copying and pasting -- that the ease of duplication is automation enough. It's nice to think that OF might be able to magically make an action appear in 19 or 78 other relevant projects, but ... software can't do everything for us. Being able to quickly paste the action into a bunch of other projects is still pretty dang handy, isn't it?

At any rate, I don't know of a better way. But I suppose if someone else does, I'd like to know it, too! :)
