Three or more wan to vpn site-to-site - sonicwall

Hi Experts,
I have the following scenario:

Site 1:
WAN 1:
WAN 2:
WAN 3:

LAN (multiple subnets) :, and

Remote Site:


In both places I have a sonicwall.

I created a vpn policy at the remote site as follows:
Policy Type: Site to Site
Auth: IKE using PS
IPsec Primary Gateway Name or Address:
IPsec Secondary Gateway Name or Address:

So the vpn works perfectly.

But I need to create a new tunnel for the third link pass to function as failover.
How could I solve this?

The high level is just setup another tunnel and set the route with a higher metric so it will only work if the first route is down.
