Launch custom folder from gnome-do

hi, and thanks for Gnome-do!

I have one question that I haven't been able to google my way to: I'd like to be able to launch custom folders from Gnome-do, not only the home folder and sub folders. specifically I wish to be able to launch opt/lampp/htdocs as this is the root folder of my localhost, and I have to access that quite often. I have tried to add the folder to the bookmarks in Nautilus, but that doesn't help.

is there a way to do this that I haven't found, and if not would it be an idea to also index the bookmarked folders in Nautilus aswell..? thanks again!
