Timesheet improvement

Hi

Just a suggestion that would help me out a lot. Could you please update the timesheet function so that I can delete a line in the timesheet without having to clear or delete the whole sheet please? Also if I could change the date and keep what I have put in would be good, I understand that would be harder to accomplish. I have often had the wrong timesheet dates and had to delete the whole thing. That would be great, thank you.
