Its not that no one knows how to solve. It is that people react more positively and will show more effort when it feels like it is being reciprocated. The issue is actually pretty easy. Also a higher barrier of entry will stop people from bothering. I don’t have Revit 2019. If the issue is all numbers and sorting, making a dummy dynamo file for people to test on will make more people try. The fact I had to make my own almost made me not want to bother replying.
Edit: Updated to simplify a few nodes at the end.
