Request: State Stacking and Custom State Damage!

I'm looking for a script or solution for creating states that can be applied multiple times on the same target!
The ability to decide the maximum number of stacks for each individual state would be appreciated!

In short: I'm looking for this: https://forums.rpgmakerweb.com/index.php?threads/stacking-states.14110/
but for MZ.

Furthermore, I'm also searching for a way to customise damage dealt by a state!
Basically this: https://forums.rpgmakerweb.com/index.php?threads/ellyes-state-damage.48631/
but for MZ.

Also the damage dealt by the custom damage script should be stable (I had that in my VX Ace Project, though with a different states customisation script)!

Thanks for listing!
