Project setting for absolute paths

I've noticed that with the current version of Delphi (Berlin) the project file (.dpr) uses relative paths and when you manually change the paths to absolute paths and then add a something to the project (e.g. a .pas file) it converts them back to relative paths.

I prefer to use relative paths, however the problem I have is that both the MD and the Development Manager at the company insist on using absolute paths, the MD seems to think and apparently has heard that using relative paths can causes problems. I cannot find any project or environmental setting to force the paths for the project files in the .dpr file to be absolute. Does anyone know of such a setting or why relative paths in the .dpr file cause problems?
