I think it's currently somehow broken due to some other changes in GUI
which were not reflected in this dialog. I will try to fix it, probably in
the next weeks. I will actually need this functionality, too.

I think it requires numbers but I am not sure if it is the problem of GUI
or underlying module (the latter I guess).
