hmmm... so I guess there is no way to get a default tie-off?

OK, that's exactly what I'm looking for.

Let's see if I understand what you said:
1. I create ATMEGAx8-1, ATMEGAx8-XTRA-1
2. User sets "device" to one of ATMEGA48<foo>, ATMEGA88<foo>, 
ATMEGA168<foo>.  Must that be done for the -XTRA part, also? Or does 
only one symbol need this attribute?
3. User sets "footprint" to whatever.
