I believe you can drag & drop the file into MobileSheets while viewing your song and it will create a smart button from the linked file. There is currently an issue where the page doesn't refresh after the button is added, but if you tap to hide/show the overlay, it will appear. I will get that fixed for the next update. If you need to reposition the button, long press and drag it to the next position.
