Ah! Ok, what you're describing is how Region Automation was implemented and displayed in the earliest version(s) of LPX (10.0.0)â€”what version are you running? I can't remember exactly in which version it was changed to what you see in my original screenshotâ€”maybe 10.1? (My screenshot was taken in 10.4.7â€”actually the most current version is 10.4.8 which adds additional under-the-hood improvements for Catalina).
That said, I'm not sure why pitchbend might be greyed out for youâ€”AFAIR it should work the same way, more or less, despite the different nomenclature (though there were lots of bugs in some of the earliest version(s) of LPX). Obviously I can't duplicate your setup exactly with the newer version of Logicâ€”is there a reason you haven't updated (older macOS, maybe)? The video below is from an older course that dates back to what I think must be LPX 10.0.0â€”take a look at around 01:43, I assume that's what you're seeing..
