Hello @camunda_kon ,
I guess this is related to our latest conversion:
Currently, there is no way of linking files in the Desktop Modeler (also not BPMN → BPMN or BPMN → DMN).
At the moment, this is solved using linking by Id which is resolved at runtime. For Camunda 8 forms, this will probably also be the first step (use a “form ref” instead of a form key which points to the form id).
In order to be able to resolve this information as links, some kind of context would be required.
I was thinking about this also some time ago, yet I do not have any information if this is in the pipeline.
