RBW30 as an extender of Orbi RBR40 with different SSID

My RBW30 satellite has basically turned to poo.  It works on Factory Reset with some channel changing for about 7-10 days then craps out again.  I've realized since I've unlugged in that I don't really need it except for one device in my house.  I was wondering if I could configure it to be an extender of my Orbi RBR40 but broadcasting on a different SSID.  This way only that one device will connect to it and my other devices won't try (which they currently fail to after 7-10 days).
