2 x Inbound NAT to same port

I need to NAT separate Public IPs to the same port but different inside IPs and cant work out how to do it.

R81.20

Scenario:

1.1.1.1 inbound to LB on port 22 >> Backend Pool >> FW >> inside destination 10.1.1.1 port 22

2.2.2.2 inbound to LB on port 22 >> Backend Pool >> FW >> inside destination 10.2.2.2 port 22

I am using clustered cloudguard gateways with frontend and backend load balancers as per standard Cloudguard Azure deployment. When I configure this in the Frontend LB rules it doesn't allow same ports to be configured for same backend pools.

Error:

The backend port, protocol and pool combination you entered matches another rule used by this load balancer. The backend port, protocol and pool combination of each load-balancing rule for a load balancer must be unique.

I understand why it's erroring but can't work out how to do this via the Frontend Load Balancer. Any help would be appreciated.

Forward to a different port on the gateway?
The gateway can translate that to the correct port.
