Creating module using allegro 17.4 schematic

Hello,

I am creating a module in Allegro 17.4 PCB editor but as expected there is no connectivity information that can be matched with my existed PCB design.

My understanding is the I need to include the same module in schematic design if yes could you please briefly let me know how to create a module in Allegro 17.4 schematic?

Kind Regards,

Nik
