Jeff,
You've managed to articulate the problem much better then my original post!
I'm afraid as you've said, it is unfortunate that this isn't possible in
3.2.
I hunted around for that patch that you thought might exist that allows
multiple hosts per entry but couldn't find it. Anyone know where it might
be?
Thanks,
-Steve
