Open music folder from plugin or CLI?

Hello,

some years ago I played with the KidsPlay plugin and extended it a bit. It is executing macros consisting of CLI commands. Now I wanted to quickly add a KidsPlay macro that opens up a music folder and displays the content on the Radio menu. The user should then be able to select one of the shown tracks.

I can do that manually by selecting "Eigene Musik/Musikordner/" (in english: Own Music/Music folder) and selecting the desired folder from the menu. But I want to jump directly to some folder using CLI commands and have not found out how to achive that.

Is this possible at all?
