Hello tramach,

Thank you for reaching out to the QuickBooks Community! The reason why the fields aren't populating is that the pick list template cannot be customized to add those fields. The only templates that can be customized to do things of that nature are:

• Sales receipts
• Invoices
• Estimates
• Statements
• Purchase orders
• Bill payment stubs

To learn more about customizing form templates, this is an excellent resource. 

• Use and customize form templates in QuickBooks Desktop.

I've sent this feature request to our Product Enhancement Team, though, because I do see the benefit of having this. I'm including the steps below on how you can also send your suggestion/feedback:

1. Click the Help tab at the top menu bar.
2. Select Send Feedback Online.
3. Click Product Suggestion.

I'm a post away if you have any questions. You can reach out to me by posting a response below. Take are!
