If I’m understanding you correctly, you have 2 Sonos systems at 2 separately locations, each with their own wifi SSID.  You want the app to know that when connected to SSID1, look for system ‘Home System’.  When connected to SSID2, look for ‘Cottage System’? I don’t have 2 systems to connect, but I believe that the app will currently look for the system you last connected to, regardless of SSID, so I see where it’s a benefit.

If you are using portables though, you would connect to the same system regardless of the SSID.  Probably not an issue  as you probably only use portables in the 2nd location, or you setup both locations under the same Sonos system.  

I take 2 Moves and 1 ROAM that connect to both systems using my single Sonos account. I also have a set of 8 wired speakers that I keep in storage most of the year and then take them to the cottage for our vacation period.

 Yes it would be nice if the speakers, mostly Move & Roam, acted like a phone where once a network is logged into it is stored in memory.  So when you are in one of the memorized WiFi environments the speaker would automatically switch to that network just like a phone does.

It is my understanding that a Sonos speaker has the ability to “Remember” up to 16 different  Wi-Fi SSID’s.  The first time a speaker is powered up in an environment with a new to it Wi-Fi SSID, you need to follow this procedure:  https://support.sonos.com/en-us/article/connect-sonos-to-a-new-router-or-wi-fi-network.

I have successfully set up 2 MOVEs and 1 ROAM to “remember” 2  different Wi-Fi SSIDs successfully for our Home location and Cottage location.

 Just wish, for at least the battery powered speakers, this network connection was automatic.
