Power numbers left/right leg?

Hi all,
Is it somehow possible to see my power output per leg (left/right) through my Zwift work outs/races?
I don’t have a power meter on my bike but would like to know if legs are fairly equally strong so I can buy a left crank arm power meter….
Thanks for your help

Not in Zwift. That’s typically something you would see in a trainer or power meter manufacturer’s app.
