Yeah, I think this would be nice to have someday. Behind the scenes it's not a simple change to make. We use similar to code to post to Facebook and Twitter. And because Twitter has a character limit, we can't use vehicle nicknames—they'd be too long in many cases.
So that means we'll need to separate the two into different processes. It's something that'd be nice at some point, but probably not in the near term. Sorry about that.
