Summary: Send approval to cost center manager using parallel method

Hi Team,

I am setting up the approval workflow for AP invoices using spreadsheet. The requirements is to send the invoices first to the Cost Center Manager then to follow the job level hierarchy. I have completed the setup as the below screenshot, but when having multiple lines with different cost centers, the approval notification is working in a serial bases but not parallel, meaning if I have two invoice lines with two different cost centers, the notification will go to cost center manager 1 and after the manager will approve it will go to cost center manager 2.
