I added better cuttoff from the print-screen.
As you can see, the times are filled, as during one week I have three different groups of the same course. In the attached printscreen, 1-3 are in the 1st week, 4-6 in the second week.
However, dates are missing there - I am usually filling only the number of weeks of the semester (which is 13), and dates are not showing up. Thus it's becoming difficult to trace back the exact date of a chosen grup in such attendance list.
Would it be please possible to add a feature to attendance - always showing up the date, with the possibility to modify it if some change teaching schedule happens ?
