[Leveler] Global to local config

Hey there, so something I've noticed thats kinda suprising to me how the Leveler cog is global settings for everything would there be a way to have a "default setting" but let server owners be able to adjust things like exp gain and such on their own that it only changes on their own server

Maybe I'm just being abit qol about this but it does limited what you can do with this cog.

My regards
