I can only think of horribly nasty solutions.  If it was me, I would re-visit the fundamental design and ask questions about what the actual intent is of the requirements.  I would try and engineer a different solution.   Back to the nasty.   I think this *might* be achievable on MR by definfing the *same* SSID but configured to forward to the VLAN on the floor, and then to use SSID availability tagging to only enable the SSID with the matching vlan tags for just the APs on that floor. https://documentation.meraki.com/MR/Other_Topics/SSID_Availability   For example; on SSID-B, create the SSID with forwarding to VLAN201.  Then only apply this SSID to APs on floor 1F. on SSID-B, create the *same* SSID (again) with forwarding to VLAN202.  Then only apply this SSID to APs on floor 12.   The WiFi SSID screen in Merai will show 3 identically configured SSID-A and thee identical SSID-B (aparting from the VLAN forwarding) based on your example.     I did say it was nasty. ...
