Scheduler, change schedule sequence

I have multiple schedules in one resource row, these schedules partly overlap.The order of displaying these schedules below each otherseems to be based on start time. The schedule with the earliest start timeis displayed on top. Is this the way it's implemented?

Is it possible to enforce the sequence ofhow the schedules are displayed, for instance in my application I need the schedule with the highestpriority to be displayed on top? I tried by changing their sequence in the datasource, but it still displays the one with the highest priority on top.
