According to the Before the Dawn page. Yes she did appear.

I'm not sure but. I'm pretty sure she's part of the bat family and she became batgirl and the only female robin. Both costumes are being worn right now. Unless something happened to the Current Batgirl or Robin, I don't think she will join the team.
