Block calls for many time ranges in the 24 hours

I have Xiaomi Poco F3 running on Android 13, fully updated. I know my relative is aging fast in the last few months, so we normally call each other 4 to 7 times a day. TODAY: I visited her at 11:20. At 14:05, she had already called me three times. So, to put down a little stress on me, meanwhile letting her keep her phone, I thought about taking a selective blocking action on that number. Says my phone refuses her calls: * from 00:00 to 08:30 * from 09:45 to 12:30 * from 13:30 to 16:30 * from 17:10 to 18:45 * from 23:00 to 00:00 While I may call her anytime, **she will be able to reach me** only on the usual timetable: * Coffee time 08:30 > 09:45 * Meal time 16:30 > 17:00 * Supper time 18:45 > 23:00 ***BUT NOT DURING WORKING HOURS AND NIGHT***. Meanwhile, all the other calls are as per usual I couldn't find any leads to a practical answer on the web. Only generic-non-useful-well-known.
