Opening links in the same tab

I have created several reports for our operations department that are all combined in an app. We use a touchscreen where the users are able to easily select and display the reports which all have their unique URL. By clicking the link, the report will open up in a new tab (even though it is part of the same "app"). There should be an option to have the URLs open in the same tab - especially if you are inside the same app.

I found out that this topic seems to be around here since a couple of years already. It is unbelievable for me that this still has not been solved yet (added as an option) after this long time.

I have no hope that this will be solved anytime soon, so I would be happy about any suggestion / work around that someone can come up with. Is there maybe some extension for Google Chrome, MS Edge, Firefox that you know of?

Regards
