I would love to ask anyone who might be willing to add this none gameplay adjusting mod.

I would love to be able when making a random match with freinds or AI to be able to say start age Dark Age and the end age to be Feudal Age. this way i can play the game on a random map without knowing the map from having to make it a custom.

Can anyone help me achieve this as i realy think this would help the game Alot for those players who DONT want trebuchets and mangonels and advanced units.
