How to route traffic through one gateway?

I have three gateways balanced to the internet. I want a certain IP on the private side of my router to stay on one gateway. I can’t figure out how to make the table in version 2.9.41.

I setup the rule for src-address=192.168.2.100 dst-address=0.0.0.0/0 and then set the interface I want it to go out. I thought you had to create a table first?

I know there is a post on this somewhere because I used it before, but can’t find it.

Use mangle to identify connections you want to route to speocific gateway and mark them using route-matk.

In /ip route add static route but set route-mark to match only connections previously route-marked…
