Sometimes I'd like to show an infinte scroll (mostly horizontally) in my prototypes if that's some services CTA's or a gallery. Currently, this isn't a feature so I ended up duplicating the whole group and adding a note in my email when I send the design over. If there was an option to make a scroll group infinite ie. as it reaches the end of its scroll it mirrors it from the beginning that would be a great help. I've shown on this quick mock up how the option on/off could look.
