Block Service & Schedule Multiple Timeframes

Currently I am only able to select one Schedule that applies to the IPs I reserved and placed in the Blocked Services section. (Advanced -> Security -> Blocked Services / Schedule) This is not ideal as I must enter two schedules to block services to my son's devices for the timeframe desired. For example, he should not be able to connect his wireless devices from 10 PM until 6 AM the following day. I am unable to find a way to do this currently. I submitted one schedule from 22:00 to 23:59 and another from 00:00 to 06:00; however, the Blocked Services section does not allow for multiple schedules. I saw similar complaints in the forums dated 2015, so I'm wondering if this has been addressed in firmware or if it is an ongoing problem. I'm running V1.01.15
