Pick one default gateway.  On that gateway define the routes for the
subnets.  When a client attempts to route through the gateway, if the
gateway knows of a shorter route for the client, the gateway should
(unless you disabled it) send an ICMP Redirect message back to the
client.  This Redirect message will cause the client to create a route
to the correct gateway.

That's the easiest way I know of.  If this doesn't help you, then I
didn't understand the problem.  Maybe a network diagram would help, in
that case.
