Checkpoint - Separate interface for RA VPN and S2S VPN

I have a R80.30 cluster which has two external connections - ISP1 and ISP2.

For our Remote Access VPN, ISP1 interface is chosen under IPsec VPN | Link Selection. However, I am turning up a S2S VPN to Azure and want to use ISP2 for that connection. How is this achieved?

I have done a bit of googling but did not find anything besides sk32229 which is very old so I am not sure if it still relevant.
