Obviously it *would* be more convenient to just let the engine handle the
messy details; I don't dispute that in the least. In fact, I think I agree
with you, and Alex, that such a thing would be good. All I'm sayin' is, if you
(or anyone else) need this feature *right now* (as opposed to whenever RunRev's
demon programmers get around to adding this feature to the engine), it should
be possible for you to implement it yourself in one form or another.

Me, too. But seeing as how the currently-necessary workaround isn't *that*
grotesquely inconvenient, I am unsure that it's worth the bother of tryna
persuade RunRev's demon programmers to fix it...
