Yes, there’s a feature for grouping projects up into Project folders. It’s a handy feature when you have more tours which you wish to show to one client - now you can send one link instead of multiple of them. It really helps you keep your tours organized in the most orderly manner possible.
Using it is very simple, just go to “New” tab on your user interface (upper left corner) and choose “Project”.
As you create a new folder (which will appear now on top of your user’s interface), you will be able to drag and drop your tours inside.
