FortiGates and VRF

I am currently in the process of evaluating FortiGate firewall to be deployed at customer locations. The plan is to use IPSec tunnel between the FortiGate and a VPN gateway (Cisco or FortiGate) located in the data center. The plan is to share the same VPN gateway (pair to be precise) for multiple customers. On the Cisco platform I am used to using VRFs which allow the data traffic from customers to be separated. One of the options I will be considering is " VRF Aware IPSec" feature available on Cisco routers. Is something similar possible with the FortiGate firewalls? Should add that I don' t want to use VDOMs as the plan is to keep the tunnel end point IP address the same for all the FortiGate firewalls that are deployed. Thanks
