Thank you for your purchase, glad to hear you like it!
Unfortunately DisplayFusion can't do what you're looking for. That bezel compensation how-to is for splitting setups when you've already enabled bezel compensation with Eyefinity or Surround.
I've never come across any software that can simulate bezel compensation. The only way I'm aware is by using the Eyefinity and Surround control panels.
Sorry I couldn't be of more help!
