Stop other players when starting to play

[Yala]

Hi, 

I tried to use Poweramp music player on my car head unit. On this unit I sometimes switch between the radio app and Poweramp.

The problem is that when I start playing music on Poweramp, the radio app keeps playing. They both play together.

This makes me to go back to the radio app and manually close it.

Is there a way for Poweramp to auto stop other players when playing is started?

Thank.
