When I create a pivot table in the Attendance Report app, both 'Hours Worked' and 'Extra Hours' are displayed in the hh:mm format. However, when I download the report, they appear as float numbers.

I want to create an xlsx file with the hh:mm format for these two fields.

I tried changing the logic in pivot_model.js, but it seems to affect the exportData() function of all pivot views in the system.

Is there a way to do this without affecting all pivot views in the system?
