Feature request: Batch "Fit Artboard Height"
I can select one Artboard and use the Fit Artboard Height ctrl + shift + A command with success.

I can sometimes select two Artboards and use the Fit Artboard Height ctrl + shift + A with success.

At present, if I select a greater number of Artboards, say qty 20, I am unsuccessful with the Fit Artboard Height ctrl + shift + A. 

If the functionality for multiple Artboards is not a confirmed feature, I'd like to submit a request to support batch Fit Artboard Height functionality from this command in Sketch Mate.

Really appreciate the time and effort invested in this Sketch plugin. 

Thanks!
