Yes that feature still needs a lot of improvements.   No harm in adding your input to the suggestion forum.     I think that was discussed in the link I posted earlier but possibly not the basics.  Right click on your User Library folder and  select New > Image  it works the same way as 2d plants.   You could try applying your panoramic to the inside of a polyine solid cylinder as a material,  which can be rotated to correct the orientation.  This works fairly well
