Export exel with month

I am trying to export my gantt chart to excel but instead of the date range for each block being per day I want it to be per month but when using the gantt.exportToExcel it only lets me export it per day

Previously, there was a bug with Excel export that allowed to export the data only with the default scale (day) and the tasks couldn’t start or end in the middle of the timeline cells. But recently, that bug was fixed.
