Subtitle, or per-post info?

I think you misunderstand. Quick Account Switch ("QAS") is very easy to do, but that's not what I'm looking for.

Basically, I'm looking for another field to be inserted when a user makes a post, and allow this field to be referenced in the body of the post. Kind of like a second title, or a sub-title, but instead, a user would type in the name of the personality that they are using (or, more ideally, select from a pull-down list of already-defined personalities in their User CP). They would still be using a single account for all of their posting, they would just be providing additional information when they post.

Does that make sense?
