Setting Flash Exposure Compensation (FEC) on EOS-M3

I am trying to map FEC to a button via the 'custom controls' area available in the camera controls section and cannot find a means to map FEC to one of the customizable buttons - has anyone had any luck with this?

Also, are the two ways below the only way to invoke FEC?

Camera controls (in shooting mode) via INFO button
Shoot menu #3: Flash Control -> Built-in flash settings -> exp. comp.

Thanks in advance!
