a-fluidsynth default

Maybe I’m obtuse and just can’t find it, but is there a way to set a default soundfont file for the built-in fluidsynth?

I generally use a GM compatible file, but when importing a midi file - 1 track/channel - I then have to manually set the soundfont for each track before use.

Thanks in advance…

A plugin-preset can work (it saves the .sf2 file used along with it)
