Love the game.
Might I suggest that an enhancement be implimented allowing the user to set a hub for reinforcements to be moved to. Say St. Louis in the west, Cinncinati in the Midwest, and Washington in the east? User could designate these either in the setup or on the Draft Page. It would speed up game play and organization and prevent units from being overlooked and then sitting unproductively in out of the way cities. This would be historical, as in reading WT Sherman's biography he lamented the fact to the war department that all the new regiments were being sent to St. Louis and Washington leaving a gaping hole is Kentucky (He was in Lexington with a few militia regiments. The player could them send a few good commanders with training attribute to the city to muster in and train the regiments. It would reduce the 30-40 minute turns by reducing administrative tasks.
