Forcing to specific port in SD-WAN specific website destination request

Hi, community

I wonder if it is possible to instruct NGFW to use a specific port in SD-WAN when a user wants to reach out specific website. I created a rule on SD-WAN Rules where all users that want to reach a specific website redirect that request to the specific port where one of the ISPs is connected. But, it doesn't work. The website request always has been redirected to our main ISP port is connected to.

Thanks
