How to automatically replace reference designators on PCB

Hi,

Is there possible to place automatically reference designators on the PCB (Allegro 16.6)? I mean the function similar to i.e. Altium that can automatically replace designators in the predefined order and orientation. I need to generate an assembly drawing for my PCB which has around 900 components on both sides, and I don't want to replace manually each of the reference designator text.
