[Dynaworks21] Navisworks count element selection set

I want to extract the number of selected elements from the selection set in an NWF file using the functions of the Dynaworks package. The NWF file contains multiple appended NWC files, and I would like to extract the number of elements for each NWC file. How can I achieve this?

In the image above, I tried to use the ‘get Nodes from selection sets’ node to count the number of elements per file by filtering only the File Name. However, there are too many Navisworks nodes for each object, causing it to take a very long time. Is there a way to load only specific nodes to reduce the processing time? Help me plz…
