Custom phoneme splitting

How do you make it so that when you set custom phonemes for a word and you split the word in two notes it assigns each syllable to a note

Give each note custom syllables.

I already do that but it gets tedious and I would prefer a way to specify where the syllables break in the custom dictionary by using a symbol like a slash, for some words it does the syllable break correctly but other words it just takes the first part of the word and makes the rest silent

Sounds like you could put this is as a request that the custom dictionary automatically split words on hyphens.

You can use “+” to switch between syllables.
