How do I change the action for Force Click on a Force Touch trackpad?
I found this tool called BetterTouchTool

  BetterTouchTool is a great, feature packed app that allows you to
  configure many gestures for your Magic Mouse, Macbook Trackpad and
  Magic Trackpad and also Mouse Gestures for normal mice. It also allows
  you to configure actions for keyboard shortcuts, normal mice buttons
  and the Apple Remote. In addition to this it has an iOS companion App
  (BTT Remote) which can also be configured to control your Mac the way
  you want.


It allows me to set a HUGE variety of actions for TONS of mouse gestures.

I am able to create actions for FORCE click on specific areas of the trackpad, and even multifinger force click.  It is exactly what I've been looking for.

It is extremely useful.
