Can I have my daughter's tablet always locked but her phone always unlocked? - familylink

I use, and like, family link however I'm a bit confused. My daughter has a tablet that she gets to use for Roblox etc on weekend mornings and evenings, but I want her phone to be able to be used at anytime besides downtime.

It seems what I want to be able to do is to set a daily limit of 2 hours on the tablet for Friday, sat and Sunday and no limit on the phone. However I can only set the same limit on both devices (setting to two hours on Friday gives two hours to phone and to tablet)

Is there a way around this besides having to manually lock the tablet daily?
