It's great to see you back in the Community. I hope your weekend was great. Allow me to give you some insight into adding a column to a journal entry in your QuickBooks Desktop (QBDT) account.
I can see how this would be beneficial for your business. However, you won't be able to modify a journal entry in your QBDT account. I'll send feedback to our Product Developers so that they can consider editing journal entries in the new release for the product. Our Developers take the time to review every request and work them into the next update for the system.
You can cruise on over to our QuickBooks Blog to track what's new in the system each time an update is available. If you have any other questions or concerns, don't hesitate to ask. I'll always be around to help. I hope you have a great rest of your week!
No, there is no modification of the JE screen other than Class and Billable, which can be removed if you turn off both Class and Billable. Otherwise, Account-Debit-Credit-Memo-Name-Billable-Class is all you get.
