Would Love To See More Customization/Custom Information

I don’t know how hard this would be to implement into the current workflow, especially as I know this is based on the default/normal D&D setup, however I would love to see the ability to add custom nodes/information for items, characters, enemies, factions, etc. Currently, the best thing I can do if I want to add custom effects or information is to cram it all in the description.

For example, I am trying to make a custom campaign/world around a modern times zombie apocalypse style scenario. In this I am implementing guns, hunger and thirst, scavenging, etc. Currently I am trying to implement things like bullet counts for specific guns/specific magazines and the only place I can put this custom information in is the description. Same with the hunger and thirst. How I am getting around implementing these is to use them as the secondary and tertiary currency (I haven’t really tested this to see if it will even work)
