There isn't one for the CC; not sure about the EC.
The CC work-around is to back up the settings folders for both, then copy that folder backup in whenever you have to switch.
Not very quick or painless.
The other option is to use a name change token and slightly modify one of the character's names. IT might well be that, if the characters have 2 (or more) word names, that adding an extra empty space (or better yet, another legal character like a dash) between name parts might be sufficient. If so, it's possible (but unlikely) that if you ever get into a conversation with a GM on another subject, and bring it up, they might be able to sneak that space (or an additional letter) into the character name for you (since they have the ability to change offensive names). I wouldn't try paging just for that issue, though.
