How can I change the Root-Path-Text of Highlighted Content

Hi, I'm looking to change the Root Text of Highlighted Content webpart on a modern page.

The posts are all in the same Site Pages Library and can be filtered by chapter using a column. Since they are all on the same site, this site is specified in the path, which makes no sense since you are already on it. Is it possible to replace this text with the value in the column?

Or am I doing it totally wrong and I need to create subfolders in the Site Pages Library or create subsites? Which would not be practical, because I would have to create many subfolders/-pages for every chapter.

Any guidance would be much appreciated
