Fader movement halts macro

If I set a macro to fade a master over a 30 second time period. I cannot find anyway to stop the macro until the 30 seconds is up. It would be great if when you grabbed the fader, it would halt the fading macro and the physical position of the fader would stay. This has bit me multiple times if I trigger the macro early/accidentally I have to manually put my lights in the programmer so they wont fade up.

Thanks,
