Yes its not too difficult at all. I untag my different vlans in the unifi controller and disable specific wifi networks from being applied to one ap over another.
For an idea on the edgerouter side see my post here for ideas? https://community.ubnt.com/t5/EdgeMAX/VLAN-traffic-showing-as-passing-over-the-base-interface-rather/m-p/1791666#M143917
I had an issue where the data transfer wasnt showing on the vlan interfaces however I figured that out and its marked as solved.
Ping me if you need any guidance at all.
Cheers
Andy
