Mod command for missile reloading

[Xether]

I was wondering if there is a command for modifying the reload length(ex. Arbalest fires once every 3 turns) of your own customized missile weapon.

If anyone knows of such a command then it will help me greatly in a 1700-1800C European mod that im creating.

At the moment i had to modify the Arbalest and Crossbow to help with this problem but this has only helped 2 out of the many rifles,muskets,pistols etc. weapons that i have created.
