In V4 you could add multiple jingle/ add/trailers into a cart. This feature was droped in V5 and remember some talk about this at the time of the introduction to the cart wall. However it was usefull for the playing of adds/ trailers in the same set order for every show. I alway had just one cart player set for this. Yes i can get the same effect from dropping the required items on to the playlist, but is much slower to do and has to be re done for each show. A dedicated stackable add/trailer player like in V4 (with seperate output to mixer) would be useful.
