Date Picker: Fixed offset for previous/next controls

Hi all,
i would like to set a time range and step through the data in fixed intervals.
Currently, the step size is half the range.
Selected range: 2020-01-03 00:00:00 to 2020-01-04 02:00:00 (26hrs)
“Next” selects 26hrs from 13hrs later.

I would like to have a quick forward of 1d or 1w …

Any ideas ?
