how to group playlist items by directory structure in apollo player style? i.e. with hierarchical structure. now i use a custom grouping by $replace(%path%,\%filename_ext%,)
it gives a directory-separated groups, but the view is plain, i.e. with no tabs before each directory level
for example, i have a file struture like this with .mp3 files in each directory:

c:\mp3\dir1\dir2
c:\mp3\dir3
c:\mp3\dir4\dir5\dir6

in foobar i have a view:

c:\mp3\dir1\------------
song1.mp3
song2.mp3
c:\mp3\dir2\------------
somefile2.mp3
somefile2.mp3
c:\mp3\dir3\------------
somefile3.mp3
somefile3.mp3
....

in apollo i have a tabbed view:
mp3
.....dir1
..........song1.mp3
..........song2.mp3
.....dir2
..........dir3
...............somefile3.mp3
...............somefile3.mp3
..........somefile2.mp3
..........somefile2.mp3

i replaced spaces with dots in case of formatting issues.

so can it be done in foobar?
