Cueing with Palettes and changing fixture types

I'm wondering if it's possible to have the option for a channel to have all attributes (whether they exsist or not in the fixture) to reference a palette in a cue?  This would allow me to change the fixture type and any new attributes are not "home" value in my cues?

a practical example would be I cue a touring show with vl3000s.  the next venue has vl3500s.  when I change the fixture type, the shutter attributes have no value in my cues.  I'd like them to always ref the palette so when I update the beam palette to include shutters there's no further programming necessary.  

Does this make sense?  Is there a better way to approach this?

Thanks!

Nick
