Ground Plane and XMP

Is it possible to export and reuse the ground plane I set onto a different project?
After alignment, I've adjusted the ground plane and export the .xmp, copy and pasted it to the next scan folder, then renamed it.

This lets the next scan to be scaled the same as the previous scale except the ground plane.

Resulting to the exported .obj with different origin:

I appreciate any help you can provide. Thank you!

  Hi Ondrej Trhan CR.
  
  Thank you for your quick response. I've watched the 2nd part of the tutorial but it doesn't really explain how did they do it. At least the part where the ground plane is preserved.
  Part 2: https://youtu.be/o09FwOw6d94
  
  At 1:09, you can actually see the alignment to be tilted towards the front, even facing diagonally relative to the grid:
  
  Then on the next step 1:18, it was positioned correctly:
  
  This is the exact problem I encounter when using different image dataset.

  Hi, I already tested the dataset, which is in the video and it worked for me. It is possible, that there is not used XMP file in mentioned alignment and that is why it is tilted.

  I aligned first image dataset, placed control points with coordinates and aligned again.

  

  Then I exported XMP as exact. Copied XMP files into folder with second set of images (the names of images and XMP files have to be the same) and open these images in new project. Then I aligned the images and the coordinate system is the same as in the first case:
