Filtering pitches in a custom Tonality System

It is not possible to filter-select microtonally inflected pitches when using a custom Tonality System. I don’t know if there’s a plan to make this work in the future, along with transposing functions and Shift-I which likewise don’t work, or work poorly, in custom Tonality Systems.

But I have a suggestion that would be quite useful, perhaps also for standard notation, and does not seem difficult to implement. In addition to “select E flat”, “select E natural” etc. there could be an option “select all the E’s, whether chromatically altered or not”. So, when in the G clef, all the notes on the first staff line would be selected, whatever the accidentals. This selection would work for any microtonally altered notes.

Thanks for the suggestion, which I’ll certainly bear in mind.
