Adding BTT to a 2nd computer

I have a 2nd Mac, in my workshop. If it matters, it's a different building on the same property as our house. I do most of my work in my house, on my iMac in my study and this is for controlling machinery and doing design touch-ups in my workshop.

I want to put BTT on this 2nd computer, so 2 questions:

  1. Do I need to buy a 2nd license? (I'm the only user of both computers)
  2. Is there an easy way to copy the configuration from my iMac in my study to the MacMini in the barn?

Found it on this thread after more searching.
