The Ability to put in items as the Icon from your inventory

[ItLucifer-MRPG]

Suggestion
Currently you can only pick an icon for your currency off of the selector. I would like to have the option to select in items from your inventory as the icon.

How would it benefit others?
This would allow for people to set currency with Custom Lore and Custom Model Data.

Additional context
I have a resource pack on my server, which I use to add Icons and make custom lore items have a different model, Id love to be able to use a custom model for my Currencies
