3 WAN connections all have same gateway? need to load balanc

I have an upcoming config, 3 DSL connections into a MK router, all 3 from same ISP and all have the same gateway assigned (pppoe).
Each DSL line has a /27 subnet routed to it. which is fine. But to load balance (I can use routing marks OK), but I technically have only one gateway?
I wanted to mark based on subnet, and just send the outbound traffic down the same WAN interface/subnet it came in on. I just cant get my head around on how to do that.

Any ideas?

use interface routing in v3

Hmm, interface routing, sounds interesting, except the v3 part, (means an upgrade which means downtime).

But it might be just the ticket, thanks! Any docs on this feature?

use interface name instead of gateway’s IP

at least in command line

This is the same like my post:
