Domain Filters for Forge and Grave Domains

[Tielc]

I noticed that there's a filter in the Spell List for things like Cleric Domain, however Arcana (SCAG), Forge and Grave Domains (Xanathars) for Cleric aren't listed there. Is there any way to add these?

Hmm. I don’t think so offhand. Those are created in the spell list in the PHB which doesn’t contain the domains from other products. I’ll have a look though to see if there’s anything that could be done.
