Can we spefify the initial image pair in colmap.py?

[lemonci]

I am trying to compare the quality of multiple GS model after adding more images.

However, as the initial image pair of the colmap cannot be fixed. the camera poses of the input images are not the same every time and makes the comparison difficult.

Any suggestions to change/call convert.py so that the camera pose of the same image can remain the same after colmap conversion each time?
