Different customized tooltip for each column in the Matrix

If a report contains a Table showing multiple columns, it would be nice to have a customized tooltip for each of the columns.



Scenario: Tooltip contains one graph showing last 7 days of sales. 

What is needed: Tooltip should dynamically show graph with last 7 days of total profit, returns, and so on .



As of now, I am able to have a customized tooltip for a sales column only, but when I hover over to profit or returns, I still see the same weekly sales graph.
