As it is, when I mark up confusing music I sometimes use an upside-down "V" to indicate semitones, "=" to indicate 'same note' and a square bracket (like upside down "|__|") between notes to indicate a tone. This is occasionally useful to me as an aide-memoire, in stuff where we have lots of double-sharps and flats, but it's certainly not "standard".
I can’t help but point out, just FWIW, and intending this in a tone of respect, and as one consideration among a host of others that might outweigh it...
...that this kind of annotation wouldn’t be needed in a system where the differences between intervals (semitone, tone, others...) were clearly and consistently represented.
