Scrolling preset steering wheel radio

[Tramline]

I’ve just got a 2018 mk3.5 Leon estate xcellence, really enjoying it and have set up the radio presets on the infotainment screen, but how can I get my steering wheel buttons to scroll just through my preset stations rather than all the available stations? Grateful for any help, many thanks!

Pretty sure the left/right button swaps between your presets rather than the scroll button.
