So, today I decided to find out how to work around this, and turns out it is possible, you just need to do some registry magic.
Here's how:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies
Create a new key named 'comdlg32'
Create a new key in that key named 'Placesbar'
Create a new string named 'Place0' and type folder (MyComputer)
Create a new string named 'Place1' and type folder (E:\[Work]\[proj_x])
Create a new string named 'Place2' and type folder (MyDocuments)
(for clarity, this is where all the strings are located: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\comdlg32\Placesbar\...)
Other pre-defined shortcuts of interest:
- MyDocuments
- MyPictures
- MyMusic
- MyFavorites
- Desktop
- ProgramFiles
- Recent
Victory!
