Althought Isaac mentioned before that I wouldn't be possible to scheduled convois via time instead of percents, I think you might achieve it using waiting month time parameter in a smart way. I mean, if you make them wait a similar period of time at each stop. let's say 5 minutes as you suggested, then you may get what you want.
Obviusly, the schedule timing also depends on the distance between stops. I mean, you must take into account the time the vehicle needs to get to the next stop.
You've more info about month wait time at this topic ..
