Self Service - Multiple Selection

When configuring a button in Self Service to utilize a selection, it would be helpful to allow a user to select multiple values. For instance, say I have a service request with a selection containing "Red, Yellow, Green" as its values. Right now, if the user wants to run against the "Red" and "Green" values, they must go through the process of clicking the button, selecting the value, and walking through all of the steps twice. It would be useful if they could select both values and execute against them with a single run. Maybe have it as a configurable slide to turn multi-select on and off when setting up the input. I think it would speed things up and just make it a little more efficient overall.
