I need to make sure to show one presentation from 830 to 930, and then the rest of the day, I would like to show the normal schedule. I thought of creating 2 schedules but one from 830 to 930 and another one from 930 to 530pm. The problem is that I can't select the same display for two different schedules. The solution I found is two modify the timing in each presentation, so I would leave presentation 1 from 830 to 930, and all the rest from 930 onward. It works, yes, but it would be quicker to be able to create several schedules, as I had to edit each presentation timing, which takes time, and for sure I will have to change it back because my managers change this all the time..;). What do you think? Is there a more clever way of doing this?
