Controller lanes in PRV

[Promidi]

My normal view of the controller lane in the PRV is with "Show Multiple Lanes" disabled. 

If you have multiple controllers on a track, the Key/Pitch part of the pane lists the controllers you can click to display that particular controller's data.

If would be handy if you could hold down a modifier key (Like SHIFT, CTRL or ALT) while clicking on another controller to add that controller's data to the controller lane.  For instance I might have many controllers in a given track, but I only want to display the lane for Volume (CC7) and Pan (CC10).

While I know I could just select "Show Multiple Lanes", I sometimes use up to 20+ controllers per track, so enabling this would make the controllers uneditable.  I would only really need a few visible at one time.
