Within Teamwork, you can use triggers in board view to auto complete task cards when they are moved to a different column.
Click the options button (three dots) to the right of the column name and select Column Settings.
At the top of the column settings quick view panel, click the Add Trigger button in the Triggers section.
You will then be able to choose who should be marked as the completer of the card when it is moved to the column:
- User moving the card
- Current task assignee
- When this option is selected, the task assignee will be marked as the completer of the task.
- If the task has multiple or no assignee, the task completer will default to the user who moved the task.
- Choose from users on the project
