Grouping customers evenly by rank

DAX DAX Calculations
6

Hi All,
I’ve been able to achieve this in Excel but am having a hard time with the context in BI yet. I’m attempting to do two things:

  1. Identify a customer as a Grower, Decliner or Defector based on YoY sales.
  2. Group these customers in even groups of 10 by their yearly rank.

I’ve been able to achieve the customer growth definition based on a measure but it’s not dynamic. I’ve attempted to make a slicer but haven’t had luck. From there, I have achieved the even grouping within the Customer Table itself but again, it’s not dynamic. Any help getting me to the finish line in the attached demo set?
