How to Send Notification to Sales Person on Sales Order in Fusion

Summary:

We are currently importing Sales Orders from CPQ using a User ID (XYZ). Our new requirement is to send Sales Order approval requests directly to the Sales Person assigned to the order. However, in Order Management Approval tasks, it is not possible to designate the Sales Person as an approver. Since we have several hundred Sales Persons, creating an Approval Group for each one is not a feasible option.

Is there a way to route Sales Order approvals to the respective Sales Person? The available options in Order Management Approvals are limited to routing tasks to an individual user, the task creator, or approval groups only.
