Question: Non-Commutative and Commutative Variables

I'm working on a problem requiring non-commutative variables. I have this functionality working properly using the code below:

restart;
with(Physics);
Setup(noncommutativeprefix = {u, w, v});
 
My variables are subscripted as well. In other words, I'll be dealing with terms u0v0v1 . This all works properly under the above code. The only trouble I'm having is the terms such as v0, v1, ... , vn commutatve with each other (and likewise for the w and u). Is there a way to tell Maple that the individual u's, w's, and v's commuative with themselves?
 
Thanks for your help.
