Hi, 

I would like to know how I could add a third step verification in Odoo (V13) Time Off for approval of leaves ? 

Currently, I have the Team Leader and Time Off Officer that approve or refuse one's request, and I would like to add a third one before the Time Off Officer. 

I tried to find a way of setting things up with Studio but did not manage. 

Has someone successfully done something like this ? 

Thank you for your help. 

Pierre
