Bunker Type and Damage

I like this Idea and Plugin. Its simple and easy. 
Just one thing, Is there a way you can add the option for the bunker to take no damage? Force it to only open with key card? 
At the moment you can raid it. 

Also this part in the config:
"Types of bunkers": [
    {
      "Number of bunkers of this type on the map": 5,
      "Access level (from 1 to 3)": 1,
      "Fusebox spawn chance (0 to 100)": 50,
      "Minimum number of crates": 1,
      "Maximum number of crates (no more than 3)": 1,
      "Grade type (0 - twigs, 1 - wood, 2 - stones, 3 - metal, 4 - topTier)": 2,
      "Use own loot table": false,
      "SimpleLootTable name": ""
    },

If I set it to 0 numbers of this bunker on map. It still spawns it in no matter. 

Thanks

Hey! You can set "Grade Type 4" so that players won't be able to raid the bunker. Will that be acceptable?

By default, there are 3 types of bunkers in the config. If you want bunkers not to spawn, then you need to set the value to 0 for each type.
