How to hide alternates from Glyphs Panel in Adobe

Hello everyone!

I’ve created an alternate for the letter -a- which should only appear in combination with a few other letters. The code is: sub a’ [a s s_s.liga s_y.liga] by a.alt.001;
And I have some similar cases.

I’d like to hide this a.alt.001 from the panel Glyphs in Illustrator and InDesign. Is there any way how I can do it?

There is no way to control this.

ok, thank you Georg!
