tk_chooseDirectory multiple choice ?


A simple question (I hope so) but I could not find the answer ...
I am using the tk_chooseDirectory to select a directory (up to now
everything is ok ;-)) and I wonder if it was possible to choose several
directory ? like for the option "-multiple" in tk_getOpenFile. In fact
in my GUI I would like to select several directories...

So is there anyway to do this using tk_chooseDirectory or with
something else. If not if, it is something that would be possible in
the next versions of tk ?
