You are absolutely right, Janet. I have been thinking along this line, but 
not used it really just because everything went smooth and fast enough not 
to bother yet. However, I am often at the limits where Poser begins to slow 
down noticiably because of too many things to manage at the same time. This 
is particularly the case with several dynamic simulations applied to the 
same figure. So, breaking up the workflow where possible is an excellent 
option and easy to reassemble in POV-Ray later on.
