I never heard of smartshortcut apps, but if this is anything like Folder Organizer, then you'll need to click the "+" on the upper right corner, and click on the "more" tab. You should be able to see your short cut app there.
After creating your folders in smart shortcuts, longpress screen and select more, you then select the smart shortcut icon and it will open a list of your folders. Select the one you want and it will appear on the chosen homescreen.
