block FaceTime SPAM group calls !!!

I've been getting !@$**! FaceTime spam group calls at all times of day+night (I now turn off my phone at night), blocking ALL those numbers individually takes time and only one needs to change for it to come through again..

APPLE WHAT ABOUT BLOCKING AN ENTIRE CALL WITH ONE SWIPE ???????????????????

My clients often call me through FaceTime Audio since it sounds so much better than a mobile call, this is really getting in the way....
