How create normal custom Dayparting

Hi.

Need Dayparting work only from 09:00 to 21:00 (every 15 minutes), and work only 3-5 days.

If i use “custom Dayparting”, a have a problem with play layer not good time (21:00 to 9:00).

If i create “my Dayparting”, i don’t create repeate over 15 min or hour, only over day. How i may change this.

And if i use “custom Dayparting” with time up “today 9:00 to next day 9:05, repeat today 15min, stop repeat at 21:00” - i have a many plays layout on every 15 min.

The best approach would probably be to have a daypart 9 am to 9 pm (or use custom daypart) with repeat daily, excluding weekends(?), schedule a campaign using that that daypart.

In the campaign you would have all layouts that should be displayed between 9 am and 9 pm, with the durations adjusted in a way, so to the layout you want to see every 15min was displayed every about 15 minutes in a cycle.
