How I do use two notes in one lyric

[Robbie1299]

I’m trying to make one word go from a C to a D. There’s no way to tie them together so the two notes cover the same lyric. What do I do? The “tie” button doesn’t work. It just puts to identical notes together.

Do something like this

P.S. if you’re making a theorytab then please do not add lyrics
