I was hopeful that a custom template might do it; the content is
controlled by specific tokens in the template file (which you can
create yourself), but it looks like (contrary to the documentation),
$rootnamespace$ actually contains the folder info. One option would be
to use "namespace $projectname$" - if you can live with the namespace
being the same as the project name (which often they might be...).
You can find out about creating your own template here:

The available tokens are listed here:

(see also the 3.0 page - there is some mention there [in the user
content] of unlisted tokens).
