Inhibit fixtures from snapping on

Feature Request, inspired by a discussion which started over here:

 Inhibiting fixtures from snapping up 

Apparently I'm not the only one who would like something like this:

A feature to inhibit certain fixtures from snapping on suddenly. What several of us are looking for is a minimum fade time which would work "without fail", with the purpose of protecting fixtures and/or people's retinas.o  So this would probably best happen in Patch -- the ability to specify fade up/down times for specific fixtures. Though I could also imagine it to be an extension of Park, if the internal structure allows for adding fade time limitations.

Manual Time Fader doesn't do it, because hopping through cues (with 'timing disable') ignores the fader. Stepping through channels with Channel Check ignores it too. Setting a 'timing disable' time in Setup isn't the solution either, because as far as I can tell, that time always applies to all fixtures.
