Page Delivery - Deliver activity on multiple pages

Hi all!

I'm trying to deliver a test on 4 different pages. For instance, four different product pages. My first thought was to go into the page delivery and add a template rule "Or" to do a "URL Contains" for each page. What I've found is that you can only do one "Or" in template rules, and the rest must be "Ands". Therefore, I can only extend an activity to two pages using Page Delivery.

Has anyone had experience delivering a test to more than two pages without running multiple activities to span those pages?

Thanks!
