Add product reference and wholesale column in BO customer overview "bought products"

[GranWizard]

Hi,

I was wondering if it is possible to add columns here in backoffice > customer > details : bought product section.
Default it shows the date, product name and amount. I would love to display the product reference in a column and if possible the wholesale price in another column.

Would this be possible in relatively simple way? Who is here with a solution?

Story behind:
The reason for this it would make it really easy to create a customer account that can be used as a "loss of inventory" accounting list. I can simply scan products in my POS, link them to a custom shop customer account and get a detailed overview of products that are thrown away because the are past due date. This would save a lot of time spending in excel and stock management...
