SNMP Monitoring both Firewalls seperate in a VDOM enabled HA-Cluster

Hello fellow Fortinet people. We have a new Fortigate Cluster (AP) with VDOMs enabled (our first Cluster with VDOM config). Now of course we want to monitore both firewalls seperately. Until now we always used the IP addresses of the dedicated management interfaces. However I just learned the following two limitations of Fortigates:

«To get SNMP working with VDOM enabled: Make sure that the interface where the SNMP collector connects to is part of the management VDOM.»
«Note: Dedicated management ports on a HA Cluster will not be part of any VDOM.»

Now from my understanding this means we cannot use the dedicated management interfaces (which are excluded from the HA). Does anyone of you has the same config and if yes, how do you monitor both firewall seperate?
