Harmonics in TAB

Hi friends, tricky one this! I am writing an arrangement for solo guitar with notes and TAB. I used the Guitar and TAB option when I created the score so the TAB auto-fills as I type notes (a fantastic feature!)

In one bar (screenshot attached) the player strikes a harmonic on string 5, fret 5. The pitch created is A above the treble clef (different to the note normally found there). In the notes, I've put this as a diamond note head with a text box saying 'harm 5 8ve' and string indicator (standard guitar practise).

The problem is that the TAB is trying to place this note as the pitch normally found on string 3, fret 2. I want the TAB to show string 5, fret 5, but when I do this, it alters the note automatically. Basically, I want the automatic connection between the notes and TAB to be disabled for that one note. Is this possible?

Thank you, Dan
