Unable to Assign the Last Task Automatically After All Tasks Completed

Hello,

I have created a checklist template in the Contextual Journey category, which includes tasks such as Line Manager, Administrative Services, IT, and HR. The process begins with assigning the Line Manager task. No other tasks can be assigned until the Line Manager task is completed. Once the Line Manager task is completed by the responsibles , all other tasks are assigned simultaneously to their respective owners except for the HR task.

How to assign the HR task as the final step in the process?

To sum, the Line Manager task is assigned first. After it is completed, all other tasks are assigned simultaneously. However, I want the HR task to be assigned last, right before the application task.
