When I import many sale orders from an Excel or CSV file, the related sale person (field called 'user_id') is always the user who imported the orders. Normally it should be the user who is related to the concrete customer in partners module. I do not want to import another column with the salespersons because that would be too much work. So is there an action I can schedule or call after import that sets the correct salesperson for each order?

Thanks in advance!
