Snap End of Event to Grid

It's primarily my self diagnosed OCD that brings forth this request, but it actually has functional use as well. Primarily when dragging in swells, reverse cymbals, etc. when it's more important that the end of an event is snapped to the grid rather than the begiing.

Could be some keyboard modifier that allows the end of the event to snap, a setting (much like quantizing the end of notes in a MIDI event), or even that if you click and drag from very close to the end of the event that functionality is enabled.
