I fully support this. It makes the managing of timesheet submissions so much simpler.

The dashboard card has a filter for "not submitted". But after talking with support, the filter doesn't work.

So the Devs have added the filter option, knowing the filter doesn't work.

So the only way to check which of my team members haven't submitted timesheets is to manually look at each one. Or look at the list of those who have submitted, and work out which members are missing from that list
