Enable SAINT for Custom Link Tracking reports

The ability to classify my custom link reports (exit, download, and other) would be full of win.

When using the s.tl() function for custom tracking, we are already passing a link name as the third parameter (example: s.tl(this, 'o', 'Main Menu: Contact Us') ). The redundancy of copying the link name into a prop, setting it via s.linkTrackVars, and managing it seperately is too much to ask. Give us SAINT for our custom link data!
