Well, I don't think you would want the first option. That would hide the power connections so that you would not be able to see what rails they are connected to.
In Capture, you can select the part, and then right click and select "Edit Properties". At the bottom of the dialog box, check "Power Pins Visible". Then you can wire the pins to whatever rails you want. I THINK (check this) that this will have the desired effect of overriding the power name on the pin. Alternatively, it might cause you to interconnect all your power buses, but I don't think it does that.
The bad thing about this is that many of the Orcad parts have zero length pins for the power pins, and the pins may not be located on the part body where you would like to see them. I suppose that this is because they forgot that someone might actually want to make these pins visible. The work around, of course, is to make your own library of parts on which you want sane power pins. This is what I usually do.
