I am trying to add multiple permissions to a VIP kit that different tier levels of VIP (ie VIP5, VIP10, VIP15, VIP20) will have access too.
I have looked in the JSON file and attempted to add them manually however the Json Validator gives me an error.

"vip": {
"name": "vip",
"description": null,
"max": 0,
"cooldown": 1800.0,
"authlevel": 0,
"hide": false,
"npconly": false,
"permission": "kits.vip15",
"kits.vip20",
"kits.vip5",
"kits.vip10",
"image": null,
"building": null,

VIP20 is the highlighted error message in the validator

Is it possible to amend these variables to allow for each of the VIP groups to access this one VIP Kit?
Or should this be amended in another area to work

I was able to work this one out using a Parent Group for all of the VIP levels i have and assigning the Kit to VIP (the parent)
