Export - Use project audio folder - Change Path Folder Issue

In the export audio mixdown box, when I click ‘Use project audio folder’ but I want to go back up one folder, ie not use the Audio project folder, but use the root folder of the project instead (For example for a full track mixdown - I dont save my track mixdowns in the audio folder…) But when I click on the path window (which is currently pointing on the project), it launches a browser pointing at my desktop! This means I have to browse back into my project folder, deep in my hard drive, making the convenience of ‘Use project audio folder’ obsolete…

In short - when I click on the path window I expect it to launch the browser pointing at the path it’s currently at (my project folder for that matter), and not at the desktop.
