Pause Backblaze backups via command line

I am trying to figure out a way to remotely (via WAN) pause Backblaze to stop if from eating up all of my upload bandwidth, which is preventing me from being able to access my Slingbox, or play a movie via Plex (among many other things). I was Backblaze to use all available upload bandwidth most of the time, but I need a way to manually pause it as needed.

I've discovered that backblaze is scriptable. See here: http://www.stevenscottfoster.net/blog/2015/5/6/the-backblaze-cli and here: https://yaleman.org/tag/backblaze/

I use an app called Keyboard Maestro, which comes with a companion iOS app that allows me to remotely trigger apple scripts, shell scripts, etc. I just don't know exactly how to create a keyboard maestro macro that uses backblaze's command line controls to pause backups in progress.

Any suggestions would be greatly appreciated... Thanks!
