Above Programmer Priority for CueLists

I'd love to have a priority (60) or TOP that would allow a cuelist, whether virtual or one assigned to a fader, to playback with a priority HIGHER than the programmer. I'd found this a very useful feature when programming on a not so well known desk, and the more I thought of it, the more I'd actually use such a feature, esp. in a busking situation when meshing between stored cues and the the programmer.
