How can I add my own sounds to ezblock (web)

I can upload my sounds to the Raspberry PI, but they don’t show up in the ezblock list, The sounds are there if I use python but not in ezblock list. How can I make them show up in the select sound list.

The preset list is set in the js file of the web page and cannot be modified by the user, but it is possible to use Text block to use your music.

Thanks, I didn’t know you could use text blocks that way.
Great to know!
