Is there any reason why Meraki does not provide the ability to select a named VLAN from a per network list to configure VLANs on ports? This would help keep things consistent and simple. The admin would just select the name and the matching VLAN is configured on the port, no more remembering VLAN IDs. With Cisco Catalyst, VTP helps here for consistency.
MS firmware version 15 has named VLANs for RADIUS assignment. Not tested it, but perhaps there will also be a way implemented to use it on Port assignments. Did you give feedback on the corresponding dashboard page?
