Scene7 URL templates

I am currently using Scene7 for my company and was wondering if you can use the '$$' more than once. For example, I use $$ as the product I want to link to but I also want it to show up in our metrics system uniquely in the same fashion. So it would look something like blah.com/Product_$$?cm-_-$$. In this example, the first $$ populates but the second doesn't. Is there a way to get this to work?
