We would love to be able to get or set URL parameters via a token. In many cases we are tracking sources from outside media with a URL parameter (i.e. source=partner). It would be great to be able to continue to pass that parameter along to other URLs on the landing page with something like 'http://markeo-landingpage/page.html?{{URLToken.("source)}}. In this manner, the token would be continued to be passed to other Marketo landing pages for processing on Form Fills.
