Yes, I think so. Some of them affect each other so you will find that it is already done on some once you do the main ones, but you have to look at them all and make sure. There are often bunch of models for different actions and positions like freeze1, freeze2, death1 etc... and if you don't change them it will be wrong during that action. The main one with the name of the unit should be first and the fx last because I believe it takes its sheet music from all the others.
