Remote App and the use of the local speakers

I use the Remote app from my iPad to connect to my iMac's iTunes library. I then have the option to broadcast that music to 1) an Apple Air Port in my basement, 2) an AppleTV in my living room, and/or 3) the iMac computer speakers (or connected audio devices). There are many occasions where I would also like to broadcast the same audio from my iPad itself. Why aren't the iPad speakers available as an option? Can this be added in a future update of the app?

Thx, Joel
