P: Using Loupe Overlay with Live View while tethered

Hi, I was wondering if it's possible to bring up a loupe overlay png file in the live view window? I know Capture One has this option and as a full time commercial photographer, this feature alone is making me consider switching. I've done a tone of digging and can't seem to find a yay or nay on the subject so I'm asking the question here. Thx.
