Add "Referring Path" to Processing Rules available variables

I would like to be able to track Referrers without the query string using Processing Rules. Since I can't split a value, I want to concatenate "Referring Domain" and "Referring Path".

Unfortunately, the latter doesn't exist.

Example: Visitor comes from http://www.site.com/some/page.html?cid=trcd001&sec=1234. I want to be able to pass "www.site.com/some/page.html" into a variable.

Thanks!
