Syncing DNG Requirements using DataHub

Hello. I am using Cameo 2024x. I'm syncing requirements from Doors Next Gen using DataHub. Something I've been trying to figure out is how to bring across "Child of" links from DNG into the model. 

For example - If I have a Stakeholder Specification which I decompose into 'child' System Specification requirements. I have two modules for each spec in DNG. How can I sync the contents of both Modules at the same time?

The links will only appear in the mapping window if I have artifacts just sitting in the folder in DNG (example - the BIT requirement below) and sync the EB Sandbox folder. It doesn't seem I'm able to sync "child of" links between the content contained WITHIN my specification modules.. any help is appreciated.
