Did you know that in the case, that fixtures are mounted on the real stage in a non-matching way to the setup prepared in the grandMA2, e.g., display as orientation of the fixture to the side instead of to the front, it is now possible to adjust a Pan and/or Tilt offset for every patched fixture.
This makes it redundant to adjust every single position preset by hand to correct the offset. The Pan and/or Tilt offset can be adjusted for every patched fixture that has Pan and/or Tilt attributes. The offset can be adjusted in Patch & Fixture Schedule or in the Patch only menu.
