Replicate similar rooms, copy & paste routes in Allegro PCB 16.5

Hi, 

I am working with 16.5. I have three similar blocks - I've defined a property "Room" for components in Schematic - in my design. I have placed and routed one block in it's Room completely. Now, I'm wondering if there is a way that I can replicate those two other blocks just the same as first one? I mean something like a copy and pase. But, I want them to keep their corresponding net name or Ref Des which they have in Schematic. I saw something in 16.6 as module. But, I want to know what should I do in 16.5.

Thanks in advance,

Hossein
