Hi Chris,
Great question! Please follow those steps.
1. Create a workflow on the Resource Link
2. Evaluation Criteria $WorkItem.EntityType='Project'
3. Action: New Item - Resource
3.1. Run On: Sub Items
3.2. Filter: TargetObject.EntityType='Project'
3.3. WorkItem = TargetObject.
3.5. Resource = $Resource
Please let me know if that work for you!
Good luck!
Tamir
