What is the simplest way of verifying components pinout in OrCAD?

Hello,
I am relatively new to OrCAD. Most of my experience is with PCAD where I could open three views of the component (pinout spreadsheet, schematic symbol, and footprint) simultaneously and then if stepped through the lines in the spreadsheet the corresponding pin would highlight in both the schematic symbol and the footprint. Can I do something like that in OrCAD/Allegro or if not, then how do I quickly verify that the pin numbering is correct?
Thanks.

    So in general if they match (which is a good thing that is what you will see). If you get mismatches you will see more detail:-

    In this example I have 2 schematic parts with differing pin numbers. You can see the mismatch and would know to fix the part and rename the pin numbers to match the PCB.

    Well, that check doesn't guarantee that the Drain and Source of the transistor are not mirrored or something like that. In other words it verifies that each pin number on the symbol has a matching pad number in the footprint and vice-versa but it cannot verify physical positioning of those pads and that's where errors usually occur, at least in my experience.
