SDWAN with LINK AGGREGATION

Hello, 

Currently, we are consolidating our 2 Fortinet Standalone to 601-E HA Fortinet Cluster. We have a set-up where our complete traffic goes through the HA pair cluster which has a main Internet connection and we also have two more ISP links for the other 2 firewalls. 601-E HA cluster has two 2 * 10G aggregate links. All zone traffic uses only the LAG link.

Here my question is during consolidation can we use the same LAG link of the 601-E cluster and create two different wan zones and write SD-WAN rules based on our requirement? It would be more if there was some documentation.
