Copying and pasting same circuit block layout in Allegro PCB-16.2

 Dear All,

I have a circuit block that is repeated 10 times.

I have drawn it in Orcad capture by copying and pasting 10 times.

I did the lay-out of the block in Allegro-PCB editor.

Now when I am copying the  block, the Ref-Des of the symbols are not getting updated ( showing *) and a lot of DRC errors are coming.

Basically there is no correspondence between circuit block in Orcad-Capture & the copied circuit block PCB layout editor.

Can anybody please tell how it can be achieved by copy & pasting. I don't want to draw the same layout 10 times.
