Multiple app free times

Hi, is it possible to have multiple app free times? Normally I have restrictions for our kids for 7pm-8am during the school days. But now during the summer I want to give them 1 hour in the morning and 1 hour ipad time in the afternoon. So the app free time is not continue and will be broken in different parts. So I need at least two time slots. But I couldn't figure out if it is possible.

Thanks!
