Custom Mod Save Directories

Is there a setting to set character save folders and files to a specific, custom, location? Or possibly a way to filter just the saves for the selected mod? So if I select a mod, only characters for that mod will be listed.

This is something I’d like to know as well. I have several modded games and several different characters. Sometimes I forget which character belongs to which mod. So this would be a good feature to have.
