I'm drawing a conceptual font were the upper case is depending on the lower case. I have made alternative glyphs for zero–nine, so they will work with the same principle as the letters, A–Z and a–z.
But in the InDesign glyph window the name of the alternative "zero" becomes "NULL" which makes it hard to find/understand.
The forms of the characters only makes sense when they are together.
So, is it possible to name the alternative zero (today named zero.alt1 in FLS) so it turns up in the InDesign glyph window as something related to zero? Like zero.alt1?
