Service [Q] How to lock the volume?

Hello all,

So I have been a long-time Cyanogenmod user, and I wanted to switch things up a little bit, so I installed the latest Paranoid Android on my Nexus 4. On CM, I had the option in settings to have the volume rocker only control media volume, and not the Ringtone Volume, is this possible in Paranoid Android? So that like if I'm at the homescreen and i press volume down/up it will change the "media" volume, not the "ringtone" volume.
