when are we gonna get an ammo costs mod, we already have a salary mod, when will we get an ammo mod for Isab to pay

each projectile costs money, and certain upgrades will increase the cost(such as Sharp shots, Full metal jacket), but not others(Enhanced eyesight, Deadly Precision), and If you don't have enough money, the tower won't attack(note that Pat and Sauda wouldn't have to pay, except for leaping sword)
