Modding casualties penalties in morale tables

[LucasPiazon]

Hello, I am making a mod and want to implement casualty morale penalties from as low as 1 percent. The lowest it goes in the morale tables is 20 percent and 6 percent for recent casualties. Simply editing the wording in the table doesn't work, is there another table I can create a new morale effect in or something?

It appears that this effect can be achieved via scripting. Since I am clueless at scripting can someone help me with this please? E.g "unary_of_men_alive<0.98 then morale -10". Alternatively Is it possible to script a unit to recover 75% casualties immediately after battle without waiting for replenishment?
