Sounds like this one is hard set to use an Omada controller. I also don't want to leave native VLAN untagged in some cases. Help tip says if receiving untagged frame it inserts the tag and forwards frame to native VLAN. This seems to be the case using a Ubiquiti AP since I cannot tag it without some trouble. Other scenario where I have an ESXi host connected to multiple VLANs, I want to tag the native VLAN also. As a workaround, I've create some VLANs labelled VOID that isn't connecting to anything but would like to remove that altogether. 

I am trying out the docker Omada image but probably going to roll this one out and not bother with the controller for now. Any future option to allow some flexibility here?
