As long as they're far from the front, you can put them in a green/green passive posture and that will cut down on their cohesion loss. It might not have a big effect when they take several turns moving, but it does help. Also, pay attention to the weather, I try to avoid moving forces through those boxes in harsh or muddy weather. Lastly, you can split up your forces in smaller elements as that seems to help shave down the time required for moving in some cases, especially when you have a large(r) force operating under CP penaly.
Postman's absolutely right about the supply chain if you intend to keep large forces out west. One thing I like to do is ensure that my troops coming out of those boxes have a good defensive force to fall into. Whether that means keeping a fort garrisoned for them to go into or a force that's entrenched up for them to join is up to you. Personally I prefer a field force because I don't want a group of low cohesion units trapped and besieged in a fort. But the trenches and/or outpost will provide cover and help them recover faster, they'll also be given some devensive protection in case your opponent tries to take advantage of their weakened state.
