Is there a better way to edit vendor spell lists?
 

I have access to both GeorgeS' tools and the EoC and have yet to find a less painful way to change out a vendors spells other than directly editing the vendors one-by-one, spell by spell. Is there a way to make a 'spell set' and then have a particular vendor use that set as his/her inventory?

Use a database browser and excel if you don't like it
