Can the remote foot switches and the fob switch that hangs around the neck be programmed at different speeds? say 50 for neck and 25 for foot.

I thought that when I first set the switches up , it was an option, but I set them both at 50%. now I have a new android tablet and had to re load app and this time the app shows all devices but doesnt let me change any speeds on any switch.

also before when the two poles were paired, I could "check" both boxes for both poles to make changes, now whenever icheck one box, the other disappears. I can check either but not both.
I reloaded the app again with same results. am I doing something wrong or has the app changed.
