I would really suggest you check out our new Software Management Suite called Ops Center, in perticular the Protector(Formerly HDID) Product.
It really helps with this task and the ease of management. I'll try and make a video of it, to show how easy it is to reuse policies in Protector.
The big differentiator is your Nodes turn into Consistency groups. So if you want to add into the same Consistency Group, add the ldev ID to the node. If you want to create seprate Consistency Groups, Create a Node Group and add the different Nodes into it, to create different Consistency Groups.
If you'd like to see it in action feel free to book a demo at the CoE(Center of Excellence)
