You can Easily assign project entries. To do this, you-have two options:
Option 1: Drag-and-Drop
From the list of users on the top right, select a user and just drag-and-drop to the desired entry.
The employee is immediately assigned to the entry time. Of course you can assign multiple users to an entry. To keep things visual, the photo of your user is displayed.
Option 2: from the entry
Simply open the covered entry, then use the dropdown menu to select users.
