SHN to FLAC conversion

[Pangaea666]

Is your feature request related to a problem? Please describe.
I read that this program could convert lossless SHN files to FLAC. However, when I try to add files (or folders, if possible?), Ciano doesn't "see" the .shn files. The folders just show up as if empty when using the add files function in the program. Is it possible to make this happen somehow, even just on my end? I have a giant heap of SHN files from years back, but the format is pretty much abandoned now from what I can tell, so I would much prefer to have all those concerts in FLAC instead, so that I can actually listen to them.

Describe the solution you'd like
The ability to convert SHN files to FLAC files (and others, for that matter)

Describe alternatives you've considered
I'm not very good with terminal commands, but from articles here and there it looks like it should be possible to do with with ffmpeg.
