When the selected report view includes days (e.g. Time & Fees>Days, or Time & Fees>Amounts & Days), it seems logical to expect that the underlying data includes at least 1 column for days.
Unfortunately this is not the case; currently, the underlying data has 4 different columns for hours (Scheduled, Incurred, Difference and Future) and none for days.
Ideally, days will be shown as a decimal. For example: With a standard 8hr work day, 4hrs incurred will be shown as 0.5 days.
