Aniblock creation

Robinson

How to specify that just certain properties go into the block?  When I make them I seem to get properties I didn't change, so when I apply the block to another character things get messed up.  For example I tried to do a breathing block, which involved using a ribcage morph, a shoulders slightly up/down and a head slightly up/down.  There were only 3 keys across 60 frames (out-in-out).  When I applied it to a different character, she aquired a lot of other morphs too. 

Is the trick to generate these on base unmorphed genesis figure only?

I suppose I answered my own question.  Experimenting with them it seems to be, "yea, correctomondo".
