Durability/Wear and Tear mod?

[digitalskillz]

My campaign is implementing Darker Dungeons Wear and Tear:
https://giffyglyph.com/darkerdungeon..._and_tear.html

I'd like to be able to track this in FG. Short of writing a custom mod that auto calculates all this (would be awesome if someone created one!), is there an easy way to add a manual tracker on a weapon or shield that the player could adjust as needed? Perhaps something like the ammo counter?
Thanks for any help/guidance.

It would require a custom extension. Otherwise you could just track it in the description of the item.
