can I add properties to initWithCoder, and encodeWithCoder

Love the generation of this guys..

but - if i add another property to an object later, is there a way to add it to these methods?

I already have live templates that help - and they used to be the shiznit; but now that I can generate the entire method so cleanly using your 2.0 geneate initWithCoder method, my live templates loook slow for adding additional properties to the nscoding methods.. :)
