Navigation Landing Page in App

Hello everyone,

I created an app for our workspace so its easier to locate reports. But i need help with a landing page. I don't want to create a dashboard and use tiles to locate and open the reports. I don't like the look of them.

What i did is, i created a new report with 4 different categories and users can click the corresponding one and they will be able to see all the reports that belong for that category and a description of each. This report is the first one they see when they open the tab, so it looks like the home page. In each table, i added a hyperlink to the report names so they can open the reports. The report will open in the app but they open in a new tab. To open the reports in the same tab, they have to select them from the drowpdown menus that i added in the apps content setting (left side).

My question is, is there a way to open on the same app tab the reports when the user is selecting them from the tables i created from my navigation report?
