Organizing files and folders inside Cubase "open" window (MAC)

Hi,
I often open files from inside Cubase. The folders are crammed by files that I would like to organize from there (and not from the finder).
Is there a way to do this (like in WINDOWS) ?

Ps by the way, is there a way to always show Cubase .cpr files and not the rest (without clicking “Options” at the bottom) ?
