Reid Havens of Havens Consulting posted a video showing how to disable and customize the hierarchy controls in a Power BI visualization. This is EXTREMELY VALUABLE for instances where the Date is used in a drill down hierarchy from Year to Quarter to Month to Day. If the user chooses the wrong button, they will drill down to Quarter but it will aggregate all Q1 data from EVERY YEAR into the Q1 bucket. This is generally not what the user is looking for. They are looking to see Year/Quarter combos. I didn’t know this option was available, but will be using it from now on!
