Display Tooltip over Grand Total

[ammar_baig]

Please allow the ability to have a tooltip appear over a grand total field in a matrix. It works fine for values and subtotal, but not for grand totals. A workaround for now is artificially creating a subtotal category, but this is cumbersome.

Now the tooltip appear for grand totals but only if the matrix has row(s) and column(s). It would be good if it appears as well when the matrix only contains column(s).
