It isn't the experience I want you to have when using the Bookmarks feature to organize the items or tasks on your dashboard in QuickBooks Online (QBO), Taylor. I'll share details below to help ensure the items in your bookmarks stay available.
When you add a task or tab on your dashboard using the Bookmark option in QBO, you'll want to avoid selecting the Save icon beside it. By doing so, they stay on the dashboard or navigation menu, and you can seamlessly go through different tabs with just one click. For visual reference, see the image below.

For more details, please see this page: Understand the navigation menu in QuickBooks Online.
On the other hand, here's an article that talks about how you can modify a report and add more details to it in QBO: Customize reports in QuickBooks Online.
Please know that I'm only a click away if you have any additional questions about QuickBooks or need assistance handling reports. I assure you I'll be around and lend you a helping hand. Keep safe.
