Sketch Resize to Fit the Width/ Height

I have this idea where we can decide how our artboard should fit. We can choose to fit horizontally (based on width), vertically (based on height), or auto (like current Resize to Fit feature). Most of the time I only want to fit my canvas vertically, not horizontally.

Maybe you guys also have the same thoughts?

Attached the sketch file & the existing feature.
