How to enharmonically shift trill note?

I have this trill but for some reason I can’t get the trill note to go to F#, which I prefer over Abbb :slight_smile: Any ideas?

If this is 24-EDO, an interval of 2 with +4/24 should work.

Ah thanks!
Yes because that section uses quartertones I was a bit lost on what the two interval boxes meant. I thought the left one wanted quarter steps as well…
