Costum raids

Can you add a new feature where you can create costum raids, You can select the name and color of the bossbar for the raid, aswell as trigger some procedures, For example: {When raid started} {When new phase starts} {When raid won} {When raid lost}. You can also select how many phases there are of the raid aswell as what mobs there will be in each phase. Aswell as what mobs you have to be near for the raid to start. Maybe also select how far away the raiders should spawn. This would be a great feature for Mcreator. :)
