This may or may not work for you, but thought I'd mention it. I perform solo (guitar/vocal) and have to switch things easily on the fly, so prefer to use MIDI to change Helix presets for songs (using one preset per song). The app SetListMaker can run on iPhone or Android, and will send any MIDI (such as Helix preset change) when you select a song from your song list (with a simple tap). If you keep your Helix in Snapshot mode, then you can use MIDI to select any song/preset, and use Helix buttons to change Snapshots.
