Oh, okay. Well, the easiest way is to just make single character sheets.
Look at the default character sets - you will need to make a pose for Down Facing Left foot forward, Right facing right foot forward, etc...
Anyway, the easiest way is to just make a single file the size you want - make all the poses, and then save it with a $ at the start of the name of the file. Then, when you import it, it should work the way you want it.
