Hi Captain,
Thanks for your message.
The quick battles format is very generic and it does not allow you to
choose where to deploy the opposing force. It does extend to the
"summer" DLC. It does a good job in allowing you to set the opposing
force's stance (defend, attack, etc) and off course choosing the
composition of both forces.
As for mods, I really don't know. I don't mod too much due to lack of time.
Let me know if you need anything,
Cheers,
J
