Anyone know how to make an added subtask automatically block its parent task?

This is not possible. Unless Flowsana can do this? @Phil_Seeman

Thanks, @Christine_Bolton - @FenwayJohnny, Flowsana can do this if you are adding the task via a Flowsana “Add subtasks” rule action. Let me know if you need more info.
