I wanted to show custom Tooltips on Grids for each cell based on the value or on Insight visual to give some idea about what that number means based on some thresholds. But quicksight does not have an option for Tooltip in Format visual for those Visuals. I had to improvise and give those info in another way but it is ugly. When can we expect this option ?
