Predefine images as horizontal?

[LWR]

Hello forum!
I'm testing around here with a few shots from a panorama camera. (nothing special - Insta 360 ...)

Due to the built-in sensor, these are already aligned somewhat horizontally.
Is it possible to somehow indicate this fact in Metashape Professional without using control points or something like that? So, for example, define a horizontal line in several images as the horizontal, or something like that?

Thanks in advance!
