MYOB Invoices (app): Ability to add Salesperson

I was wondering if it is possible to add the salesperson in the MYOB On-The-Go app? It's part of my Clients invoice to include the salesperson name and they'd like to be able to do this using the app. This is a major gap in the app. Would certainly benefit business efficiency and reporting.
