I would find it immensely helpful if you could just add Archicad objects to a model based on the design option it belongs to:
Currently it is doable by creating selections to filter the elements (ctrl+F and set up the search criteria to contain the design option), but I would find it more streamlined and less error prone that way, especially for larger models where a lot of people could send in several options from a teamwork file - I could just tell them to choose the appropriate design option and that’s it.
This would certainly be a powerful function - even more so if it also was possible to compare models (view changes) as it currently is for versions in the viewer.
Your comment activated a memory from probably a Morphosis book almost a decade ago, where there was a huge branch of model evolution presented for a project - I’ll try to find it.
