HI Björn

Without specific custom dev you can do the following:

Create an Automated Action to Set Due Date

1. Go to Settings > Technical > Automation > Automated Actions.
2. Click Create to set up a new automated action with the following configuration:
   • Model: Project Task
   • Trigger: On Creation
   • Filter: Add a filter to apply the action only to tasks in the "Inbox" stage:
     • Field: Stage
     • Condition: = (equal)
     • Value: Select the "Inbox" stage (or use its ID if you need to specify it directly).
3. Action to Do: Choose Update the record.
4. In the Update Values section, set the Deadline field:
   • In the "Deadline" (or "Date Deadline") field, add the following code to set the due date 3 days after creation:

   • record.date_deadline = record.create_date + timedelta(days=3)
     

To make it consistent, I propose to add a specific stage, and then adapt the alias setting (in technical -> alias), and add stage besides the team

Hope this helps you
