You can use a URL match in combination with a funnel to enable more specific and flexible URL matching. In this example we are going to explore how to match against the following two URLs specifically /cart/payment and /checkout
First we are going to edit our URL match to the following /{+page}.
While the URL match will correctly match /cart/payment and /checkout it will also match other unwanted URLs like /register etc. To fix this we are going to add a funnel directly after the URL match to specify the values of {page} that we accept.

/cart/payment or /cart/payment/ the value of the page variable will be cart/payment
