Hi FTTrading,
Have look on the link below. It looks like quickfile is doing this automatically in the background for you. I am not sure if you can change it,may only quickfile can do it.
Allocating PayPal charges
QuickFile automatically aggregates and tags all your PayPal charges to a supplier of your choice. By default QuickFile will create a supplier called ‘PayPal (yourpaypal@email.com)’.
