hey @willem.creffierKCWFB !
One option I can think of is to get elements from the link using one of the “Get Elements Of Category in Link Document” type of nodes that are available (there are some in Archi-Lab and in Data Shapes), then create a dictionary where the value is the element, and the key is the Id or Guid. Then you should be able to get the elements by their Id using the dictionary without having to export things. I hope this makes sense !
