Influence a specific network in OSPF

We have a router that is a hub for several sites before being passed off to our different uplinks with different costs. We would like to cost a route from a specific site (1 network) to go to a “higher cost” router. Is this possible with Mikrotik OSPF? My colleague remembers being able to do this in EIGRP, but we know the two protocols have different feature sets.

So as a visual, here is the section of the network I am working on:

We want to route traffic from Router 1 to Router 3 through Router 4 without affecting the traffic to the other “spokes” connected to Router 2. Router 3 has a single /24 assigned to it.

You cannot change cost only for single route.
