How to make the variable Subscript[p,D] wholly unrelated to variable p?

For instance, the notebook...

p = a x + b x;
p + Subscript[p,D]

...produces a x + b x + Subscript[ax+bx,D]. 

But I want p + Subscript[p,D] and thereafter, to freely use 
Subscript[p,D] without it being affected by the p-value.  Symbolizing 
Subscript[p,D] didn't work.
