multiple sources folder view

[Dj YB]

hello,

is it possible to configure a folder in Dolphin or any other way to show the 
content of multiple sources?

for example the folder ~/Movies will show the content of the folders
/mnt/Disk-500/Movies
/mnt/Disk-250/Movies
~/Downloads/videos

writing to ~/Movies would write to a specified location, possibly one of the 
mentioned above.

I saw it in Win7 and thought it could be very useful.
thanks,
YB.
