Quartile split based on segmented data

Hi Power BI community,

I am working with some data that has been simplified in the below table.

What I am trying to do is split the data into quartiles based on a selected product. So if Product 2 is selected in a slicer/dropdown, what I would like is the sales data for that product split into 4 quartiles i.e. quartile 1 is the best performing countries in terms of Avg Profit (per unit), and quartile 4 the worst performing countries.. It's possible I may have certain products with sales in less than 4 countries, in which case they can go into the relevant quartiles in order from 1 to 2 to 3.

I would like to use the quartiles as visual filters after.

I've read several threads but can't figure out how I might do this, so any guidance would be appreciated.
