greek letters in combined variable names



Hi!
 Is there some way of composing variable names including greek letters?
 I meant to have variable names similar to 
a1:   <expr1>;
a2:   <expr2>;
a:  a1*a2;

 but using, let's say , greek "alpha" instead of latin "a"

 Of course, I know that one gets alpha letter by writing %alpha or \aplha  ,
but by writing   %alpha1 
you get just the same %alpha  string instead of the alpha symbol followed by a 1....

 All the best
