Is there a way to add prepared buttons to cantrips for a homebrew class?

I have homebrewed a spellcasting class that can repick its cantrips at the end of each long rest. Instead of having my player manually add and remove cantrips from their spell list every time they want to switch, I was wondering if there's a way to get the prepared buttons (that exist for the higher levels) to appear on their sheet for cantrips as well.

Not that I'm aware of. Two workaround I could think of: 1) manually copy & paste an emoji of some kind ⭕ to the start of the cantrip's name in the spells tab 2) create a spellbook macro then either use a symbol like above to mark prepared cantrips, or just have a text document with each cantrip & linked ability, one per line that the player can easily copy & paste into their spellbook macro each time they change spells. I'd go for the second option, but then I always use a spellbook macro anyway. By the way, don't copy the actual code linked above, it's for an npc sheet. It's just an example. I was feeling  too lazy to screenshot my own.
