I have one thing to figure out: How can user exclude particular rows from loaded data to be used in any expression on dashboard.
As I see it could be that there are checkboxes in last column of my table, all checked... And user can uncheck particular rows,
to make them kinda "dissapear" from database(do not use them in any calculations in current dashboard), at any time they can check them back.
Maybe there is another simple way I can't imagine..
Hope someone can understand what I meant and help me.
