How to set Open File Dialog path explicitly?

### Description I'd like to point a folder so any application will start its "File Open Dialog" in it. How can I do that? ### Rationale I'm naturally using many applications while working on a project, like FreeCAD, LibreCAD, VLC, SimpleScan, etc. It's frustrating to navigate to my work folder for every single one of those applications. If I could set such a path, any application will start that dialog within my work folder, so I can easily handle my files.
