I had also tried using the Add Inclusions component. The result was an error being thrown with the message :
Server was unable to process request. ---> The item '67c1b3f0-af82-4b88-a1bc-d149e1e30248' could not be included in the collection because it is not of type ResourceItem or INSResourceCollection.
The guid displayed in the message is from the Policy I was trying to add.
