walking/moving speed of units

[trollinguy]

I have been playing this game for months now and a thing that is kind of annoying is when you send out an army of many different units they spread out because of there movement speed and almost all die when they reach the objective. I have thought that you could regulate the walking speed to everyone that is selected you have this option to regulate speed making it so that every unit will have the speed of the slowest unit in the army. this would be really useful with units like medics and veterans since medics have a faster walking speed and die when they reach the objective leaving only the veterans in battle.

Currently there is a way to make followers for a unit. Select a group of fast units and right click on a slower unit.
Tie the slower unit to a number (ex. Ctrl + 1) and control only him while having the rest of your units follow the slowest unit.
