Separete "Job Name" for each date when importing

When importing photos that has been taken different days it would be great to be able to set separate Job Names to the different days. Maybe a token that for that option that activates a pop-up screen there on can add the job name for the different days.

Current workaround

I import photos taken for each separate day and give them unique job names, so if I have photos from three days I do three separate imports.
