Dataview: How to unknown inline variables and list their values?

Not with plain Dataview, but probably with DataviewJS. That’s why I said to put the properties in lists. It makes for a quick, straightforward query.

Hopefully someone else can help you with it. I messed up the simple regex check in the query I posted above and switched to choice(startswith( instead. So I’m not anyone’s go-to for that!

Good luck.
