Automatically switch between known wifi networks

[Beardslow55]

I found and built this project for my wife and she loves it. I'm still fairly new to programing, ardunio, github and the like but had a question. On occasion she brings her weather station home for a few days but I have to reflash it to our home network wifi in order for it to work. Is it possible to set up 2 or 3 "known" wifi SSIDs and passwords and the esp32 automatically try each one in a specified order? I'd be ok if I had to press the reset button in order for it to "scan" for the known 2 or 3 networks. Thanks in advance.
