Allow ospf to advertise one of the untagged lan subnets if multiple

Occasionally on networks that we install equipment on that we don’t control we have to use additional lan subnet on a untagged network.
However the peplinks are missing the ability to selectively advertise only one of the subnets via ospf.
Can we please get this feature added?

Can we get an update on this? @sitloongs
