I get that in real life units get stopped or suffer morale problems which slow them down. But
when my guys stop they don't seem to start again. They tend to mill around and forget where they were supposed to be going. There should perhaps be a "resume course" button.
Any suggestions? As you can see I tried a toolbar mod to see if it would help. If I was able to prevent the AI from stopping to fight skirmishers or for any other reason (is this the forced march button?) then they might have a chance of reaching the enemy and forming line. Or is the trick to use column first?
My units well formed line. After multiple attempts and the units ending nowhere near the indicators said they would be.

My cannon taking a dip and heading the opposite direction it was supposed to.

My line infantry also love to take dips
