Power Outage

I have a Sonos system which generally works well. Recent bad weather has resulted in several drops of mains power , sometimes for a few seconds, sometimes for a few hours. The result is always the same. 
I have some radio sources permanently attached to each speaker - so for example the Sonos ONE in the ‘Dining Room’ has my favourite radio station permanently connected; the speaker is simply turned on and off via the top button on the speaker.

I have several speakers in different rooms similarly setup in the same way.

After a power outage the knowledge of which radio station connects to which speaker is lost and has to be setup again.

While this is ok for me, being relatively familiar with the Sonos app I have to say that my wife - aged 80 - and with little technical skill in the system would, if left alone , be frankly unable to sort it out, rendering the system useless.

Surely this product cannot be aimed purely at tech savvy youngsters. 
 

Surely it is not beyond the wit of man to create a SAVE  and RESTORE  feature . Surely when the product is running normally one could SAVE the configuration but after a power outage a simple RESTORE from the app would be adequate to bring it back to that status.

I realise I am probably over simplifying a more difficult problem but when I depart this Earth my wife will be left with several thousands pounds (or dollars) worth of useless junk and that cannot be an acceptable position.
