There doesn't seem to be an option that allows a player - particularly useful for CSA - to demolish or at least have a percentage chance of demolishing developments (new or at start) in cities being abandoned to the enemy. Plunder is available but as far as I can see it doesn't actually remove any structures. I'd like to see this introduced as an additional regional decision card - with perhaps the percentage possibility increased through the presence for the defender of larger forces or specialised troops (cavalry/partisans?) and/or Generals with certain special abilities.
A similar opportunity to destroy supply centres in cities would also be useful.
