Wizmote remote controller - presets only 1,2,3,4 - Fource a Playlist?

Learning that the wizmote only uses preset 1,2,3 and 4. I would like to signal a playlist from the wizmote.

I tried to copy the API (json) from a playlist into preset 1 but it appears to run the previous preset 1.

Anyone else tried to use a playlist with the wizmote?
