So yeah that's not at all easy to compute, it's not really related to the bounding box, but an entirely separate calculation.

Yeah I guess something like a "projected centroid" type thing, I took a quick look around and I do not see any functionality that seems to resemble that in Solids++ so that would likely be a significant project to try and implement that, sorry.
