loot.json needs a new rule

[Rhaptein]

[{"mob": "minecraft:zombie",
"item": [ "minecraft:bone", "minecraft:string", "minecraft:feather", "minecraft:stick", "minecraft:flint", "minecraft:glass_bottle", "minecraft:book", "minecraft:iron_nugget", "minecraft:iron_ingot", "minecraft:rabbit_hide", "minecraft:arrow", "minecraft:redstone", "minecraft:emerald", "minecraft:spyglass", "minecraft:sugar", "minecraft:gunpowder" ],
"itemcount": "1-4/3-7/5-10"
}]

Problem: no rule to suggest a limit of how many random entries can be chosen. There are 16 item entries
Solution: new rule called "entries" similiar to "itemcount" rule
Example: "entries": "0-2"

ty lmk if this is already possible I've looked in the docs couldnt find it
