I am using SharePoint On-Prem 2019 and have Nitro Studio hosting my sites. One site I have manages the purchasing system, and I would like to filter the approvers based on location. I already have worflows set up for multilevel approval, but we have offices in different areas each with their own Manager, so I would like to set each Location Manager as a Level 1 approver and set it to where Location gets factored into the approval process.
Example: Someone at Office A submits a purchase request, and the level one approver is the Office A manager. How can I set it so that only Manager A gets the request instead of all managers?
