Change the order of visualization of the font family

Hello, I’m drawing a variable font with 6 axes and many instances. I would like to change the order of the instances when are fox example visualizated in Illustrator. Is it possible to decide in which order the fonts of a family can be?
What I have to do? I have to use some custom parameters?
Thank you in advance!

They are on the order of the axes. Unless you change axisorder, which is currently not possible from within Glyphs, but in TTX.

Thank you! And so how can I do it? I never use ttx

Fonttools/ttx requires a little leaning into, I am afraid. Start here:
