Starting fund in custom battles

Does anybody know how to change the starting fund (10,000 denarii) in the custom battle screen please? This is too small a sum to allow a full legion army and limits the numbers of men that can be on the battlefield.

I want to be able to fight with whatever number and type of men I like so I can try out various tactical formations and combos.

Umm.. there's a scroll tab right next to the amount. The amount can be changed up to 100,000.
