For wireless clients
Take a look at the Mikrotik connect-list and Mikrotik area-prefix
I assume you have multiple APs your clients are connection to and the APs all have the same SSID
Here is what you can do:
On your APs ( all APs have the same SSID ) , configure a unique area-prefix for each AP
On your clients ( all your clients want to connect to the same SSID ) , configure the connect-list unique prefix you want the client to connect to.
If the connect-list fails , the client will try to connect normally as if there was no connect-list or area-prefix setting
