MAX HD4, How to split the traffic from crew and admin on 2 separate sim cards / interface

We have a customer who wants to split the traffic from Admin on Interface 1 and from Crew on interface 2, how is this configured in MAX HD4?
Any suggestions?

Assuming a default config. The easiest way is to create a new VLAN (ie assign that to an SSID and any LAN ports that the crew use then create two outbound policies.

The first sends all traffic from via Cell 2 (or whatever) and another policy that sends the rest of the traffic (the admin traffic) via the interfaces you want to use.
