Display the name of an assigned price book in subform in "Invoices" module

Display the name of an assigned price book in subform in "Invoices" module

Hello, 

I am trying to figure out how to display the value of an assigned price book in the "Invoices" module. 

In the product order subform in Invoice I assigned a price book to a product. But the problem is that I don't see which price book is assigned to the product. 

Is it possible to display the name of an assigned price book to a custom field in the same subform? Please see screenshot below… 




Thanks for help, 
Michael
