Bluetooth Speaker Circuit .. Can i Add switching to have the Option for Stereo .. R + L - and Mono L+ L to the drivers

So i am working on a build .. a Bluetooth Speaker Circuit .. using a CSR8000 series Chip ...

The circuit i would like to build ideally would have switching for mono or stereo mode - directly off the BT Chip Output and before any other circuitry .. The Switching ideally electronic not mechanical

For instance -- a mode step through button .. 1 press BT stereo .. 2 Press BT mono - 3. Press Aux Stereo - 4. Press Aux Mono

Stereo Mode - the drivers will sound Right + Left .. Mono Delivers Left + Left to the Drivers .. sorry for the sketchy description ..

the speaker will be a traditional simple build .. using quality marketplace parts
