Unfortunately, such a feature does not exist in the standard functionality.
However, the Workflow approver decision mechanism in NAV/BC is not that difficult to use.
1) Define a supervisor and determine the approval route from the chain of supervisor .
2) Define the approval route for each workflow to attach the Workflow User Group.
These are the two major types above.
The second type just copies the approval route of the workflow user group to the Approval Request Entries when the Send Approval Request button is pressed. Based on this feature, I think it is better to customize it so that the approval route defined by the user on the page is copied to the Approval Request Entries.
I hope this is useful to you.
