Manual Outbound NAT with 2 WANs using failover

Outbound NAT (Manual Outbound NAT enabled)
…Host-specific rules above the last...
Interface: WAN2TWC; Source: 192.168.1.0/24; Source Port: *; Destination: *; Destination Port: *; NAT Address: *; NAT Port: *; Static Port: NO;

Because I have a need for Manual Outbound NAT to force an outbound public IP AND implement failover for the rest of my machines inside the network, my question is:
How do I configure the Outbound NAT to use failover when a Interface is required for the rule?

NAT has nothing to do with where traffic goes, it only specifies how it's translated when it goes out the specified interface.

I understand this, but I'm telling you that with without an Outbound NAT rule assigned to the specific interface, outbound traffic does not work. If I disable (unplug) my primary Internet connection, the failover works properly, but I still have to manually change the Outbound NAT rule for "everything else" to use the secondary interface.

You never change outbound NAT. You have to have two outbound NAT rules, one for each WAN, if using manual outbound NAT.
