setup multiple Downtime blocks per day via Screen Time

Hi, I would like to setup multiple Downtime block PER DAY for my child's ipad usage. For example, I would like Downtime to be on say between 8am~noon, and then from 1pm~3pm during class time, so that my child will only have access to classroom apps during the Downtime blocks.

So far, I can only seem to be able to make just one Downtime block per day (and I know I can have different Downtimes on different days). Does this feature exists in Screen Time at all? If not, can someone recommend an alternative Apps or method to create multiple restriction time zone per day?

Thanks!
