Automation fadeout playfile

Is it possible when automation is running to have a lets say at time 20:59:59 hard fadout whats playing. Then at 21:00:00 the schedule play file start without fadout during intro jingle.

Default fadeout is 4000ms as it works on most items just not the play events on certain shows.

Is there a hack using script at that time to fadeout instantly so show starts clean?

Fade in, rather?  

No the issue is its current automation that fades out while the scheduled show begins. I want the current song,jingel,file what ever to (hard stop) when show at 21:00:00 starts with event play file.

Is it doable at all without change default settings as shows are run thru event play file.
