Would we have a way to make sure the ad manager to make sure that pre roll ads. I will give a example of the issue I run into and what I would like fixed.

you start and have a 3 min ad - pre-roll is off for 60 min
after the 60 min the ad manager plays a 90 second ad for 30 min pre roll getting turn off
hour latter the 90 second ad will play and now you have pre rolls off
10 min latter lets say I play a 3 min add manually, pre-roll will hit the cap and be off for 60 min but the add manager turn off the next 2 90 second so what will happen is after the 60 min you will have pre-roll for 20 min until the next 90 second block, to get back on the disable pre-roll ads again. At this point you need to manually have to run ads for the entire stream.

My proposed idea would be a way you can have it set up as, "if pre-rolls where to activate play X amount of ads" (30,60,90,120,150,180). this would allow us to play more ads when we have a dip in the action where a ad break would be perfect without having to worry about breaking the ad manager.
