Is there a way to customize the Gantt Chart's Timeline tooltip(s)?

I need to be able to customize what the tooltip shows when hovering over a cell on a gantt chart timeline. I have the cell contents formatted the way I need with a custom formatter, but the tooltip seems to only show what the displayed contents of the cell is, which is not ideal.

For the example above, I have the cell displaying the week number, and would like the tooltip to show the week dates {dd-MMM-y}

Hi Richard,

Greeting from syncfusion support.

We would like to inform you about the behavior of tooltip rendering in Gantt Chart. The value append inside the title attribute of the header cell element is rendered as the tooltip for the header cell. If you want to customize the value inside the title attribute you can be able to achieve this by picking up the class name e-header-cell-label and then you need to change the title attribute value.
