You're absolutely right. The unison width is still in effect when the soft pedal setting is at max. Even on lower notes with two strings per note.
The only reason I figured out that the "Soft pedal" controls una corda is because of the pop-up tooltip when you hover the mouse over it. (And there is no other soft pedal on grands; something I'm not that used to, having grown up mostly with uprights, where soft pedal is a bit of felt between hammers and strings.)
I guess for now the best you can do to emulate a single string per note is to set the unison width to 0 and adjust the soft / una corda pedal setting and/or tweak the hammer hardness.
If you muck around for long enough you can get a sound very similar to the Una Corda instrument (or at least the way it sounds in the demos I was going by). I spent longer on making it than it took me to get bored with the sound and want the proper piano sound back. But I encountered other useful/interesting virtual instruments along the way, like pizzicato strings-like sounds and plucked double bass.
Oddly enough there seems to be no note-by-note adjustment for the soft pedal setting in the Pro version.
