In the faction files CW2 > GameData > Factions
Open the relevant files (1-USA & 2-CSA) using Notepad and add the following line
LdrNameInHQ = 1
I added it just after HQStackName and it worked fine but I think it can be added pretty much anywhere after UID
You will then end up with Division Names like
J Reno's Divison
J Reynolds's Division <--

But for those who like a bit of flavour I am sure you can avoid the use of those generals
