Automate Continuity reactivation post-update?

I've got an early 2011 MBP with an upgraded AirPort card. I know that one has to jump through kext- and Terminal-based hoops to enable Continuity, but I also know that Continuity Activation Tool does the entire process at the press of a button. The one problem is that whenever I install a software update or reinstall Yosemite, it undoes the Continuity-enabling process.

My question: Is there a way to make the Continuity-enabling process automatically run after every update/reinstall?
