Generate invoice/report for a given fine-grained period (hh:mm accurate)

Test result

AFAIK sadly missing for invoices, i.e. it does not detect which job events ("Slips") are within a chosen time bracket, one has to painfully select each Slip (check a checkbox) from within a table of slips (the line items of which are BTW not able to be opened to the Slip properties box). The invoice creation Slips table does not even have a "select all" feature for the Slips, a real time waster.

The report generation has date filters, but only day-accurate (not hh:mm).
