possibility to use the Era 300 as stereo pair for music or in surround setting by the click of a button

As far as I am informed it is still not possible to use two era 300’ s as a stereo pair when listening to music when these two era 300’s are setup in a surround setting together with an arc and a sub gen 3.

If you want to use them as stereo pair,  everything needs to be installed from the start?

And if I want to switch back to home cinema setup, I need to install them once more?

Why is it not possible to switch between cinema setup and stereo setup in the Sonos app

It would be great when I can youse the 2 Era 300’s for listening to music or cinema with a simple press of a button.

Will there be an update to let this work in the future ??
