Split one Up2Stream AMP into two (mono) rooms?

Hi there!

I am planning to use Up2Stream AMPs to power one speaker in multiple rooms. Ideally (most cost-efficient), I would like to use one Up2Stream AMP to power two speakers in different rooms with different streams/songs.

Is it possible to switch Up2Stream AMP into mono mode, “split” it in the 4Stream App into two rooms and use L and R outputs for each room respectively?

If not, do I have any other options than using one AMP per room?

Cheers!
