Organizing projects in library inspector (left panel)

Within the library inspector or left panel of aperture, I have what seems like 70 plus projects which makes less user friendly when navigating to find a certain core of folders and albums. Can I place all these projects into a folder that I name something like "Container for all other Projects" that way I do not have to scroll through all those projects when I am looking for my core albums and folders? Will placing these projects into a folder have any effect on other folders, albums, or projects in general? Is there a negative to this type of library inspector organization?

Thanks for reading
