Hi, rennic.

Let me provide you some insights about memorizing the report.

You can memorize reports in QuickBooks if you want the same settings of the customized report to be available for future use. This way, you don't have to go through customization again. 
Once you made any changes to those reports usually changes will apply.

For future reference, read through this article to learn more about how to edit/delete a memorized report.

Feel welcome to reach out to me again with any questions you may have in customizing reports and I would be more than happy to help.
