PepLink BR1 Pro Max: SF L2VPN passing multiple tagged VLANs

We have configured a SF L2VPN tunnel between two BR1 Pro Max units on version 8.6. This is working fine, however, we have to manually define the VLANs we want to pass and select them under port settings. This is suboptimal for our use case. We want the PepLinks to just pass all frames over the L2VPN SF tunnel but it seems unable to do so unless we define what 802.1q tags the PepLink will see.

We have tried to configure every combination of access/trunk option on port2 which is bound to the SF L2VPN to no avail. Are we missing something?
