The problem is that you need to know the SSID before you attempt
association, that's simply how wifi works.  It's not a limitation of the
supplicant, it's a limitation of WiFi on any platform.

You could create a script or daemon or something that does a scan, looks
for your BSSID, grabs the SSID from the scan result, then writes the
correct supplicant config file and kicks off the supplicant.  This sort
of thing is usually handled by connection managers that use stored
configuration to direct the supplicant to associate with a chosen BSS.
