I have learned about that option today for the XG Wireless protection function "Override wireless networks’ passphrase" .
As we also have some Voucher "Password of the day" enabled SSID in Central, I'd like to know if there is a similar function. I could not find one.
This would be really helpful for us on remote locations with regularly changing guest networks. Technically for us there is no need for PSK+Voucher. A always changing PSK would be easier for this usecase.
