So in this case, since WiFi SS is pin 10, I would have to do a jumper between 10 and 53? As its a shield for Uno and up, it doesnt connect to 53 in any way at the moment.
If the shields were all designed for an Uno, and you're using them on a mega, then you likely need to jumper 50-51-52 over to 11-12-13 (check the order). D4,8,9, and 10 can then be used as CS pins.
