Add SAINT Classifications to List eVars

I set up a list eVar, and was surprised to find out that I can't classify the values once they make it to the reporting layer.

Example:  I'm passing multiple click through actions in a test using s.list2

s.list2="Clickable Link A, Clickable Link B"

A & B are part of a single creative unit, so I want to Classify them as combined Creative Unit 1, so I can measure Clicks on Unit 1 vs Unit 2.
