Cant do multiple permissions per weapon

Is there any way to set more then one mag size permission per weapon like you could on the free Firearm Modifier mod on umod,

For example I tried this but it did not work.

{
      "weaponName": "rocket.launcher",
      "capacity": 3,
      "defaultCapacity": 1,
      "permission": "xmagazinecapacity.rocketlauncher3"
    },
    {
      "weaponName": "rocket.launcher.dragon",
      "capacity": 6,
      "defaultCapacity": 1,
      "permission": "xmagazinecapacity.rocketlauncher6"
    }

Also finding the mod randomly stops working but is still loaded oxide logs are not reporting any errors so i have had to add a reload command in my server panel to reload it every hour
