Yes, and just for more information, you can add sheets and also default the number of sheets you wish. You can rename them and change colors. Thanks for a good post Martin. As a tip, you can just keep a new sheet on your desktop and slide drag it in to the left pane.
When we used them a lot our secretary just put them in with all the demographics. You can time and date stamp them, but in order to secure the sheet so no one can change it, I would recommend hiring an Excel expert. I played around with it, but it was just too frustrating.
