Hi there, @snowsnow… I don’t have data in my sandbox app to test such an expression right this minute, but it looks like you might be able to do what you described if you enable the experimental parentheses feature.
Keep in mind that an experimental feature can go away at any time (although, I would be shocked if this one went away at some point, but you never know), so you might want to be careful about building critical functionality on top of it. That being said, it couldn’t hurt to try what I showed in my screenshot.
Hope this helps.
Best…
Mike
Edit: I just tested it, and it works as expected.
