Multiple Spell Lists?
 

Is is possible to create a creature in the editor with access to spells from two different lists, sorcerer and cleric for example?

I don't believe there is a way to bring up separate racial spell list tabs in the UI without adding the actual classes to a monster and saving it in a portfolio or stock file. (Or at least I have not been able to do so).

Since you usually set Innate Spellcasting or Spellcasting by bootstrapping xInnatSpel and xSpellcast there is a way to make the statblock look correct. You can add the field "CustDesc" to either of those bootstraps and type in the description header to look right. (The part that goes "My Creature is a 6th level spellcaster (4th level Cleric/2nd level Sorcerer....). Then all you have to do is add all the sClass tags for the spell lists you have access to. (sClass.cHelpSor, sClass.cHelpClr in this example).

Thanks! I'll give it a try....

Worked, Perfect!

Just what I needed, by just adding just the sClass tags. This is a conversion of Pathfinder's Lamia Matriarch which treats the cleric spells as sorcerer spells.

Thanks again!

Spellcasting. The lamia matriarch is a 6th-level spellcaster. Its spellcasting ability is Charisma (spell save DC 16, +8 to hit with spell attacks). The lamia matriarch has the following cleric/sorcerer spells prepared:
