Grouping and Unioning chords

Please excuse me if this topic has come up before, I have a vague recollection of seeing it mentioned, but I couldn’t find it anywhere.

It would be quite useful for me to group or union chords in different ways from inside the editing window, which it allows you to do. But, as I’m sure you’re aware, these functions align the chord with the LAST note selected, rather than the first one. This is especially problematic when you’re trying to save the offsets and end up with a bunch of negative values.

I wonder: is there some good reason why it aligns to the last note, and would there be an easy fix to make it go the other way? Obviously, there are a lot of workarounds, but I always wonder if there is some bit of ingenuity to this design that is lost on me.

(And while I’m on the subject, could ungrouping be a thing?)
