Edit the part in the drawing.(right click it)
Change the pin value from VDD to 12V or what-ever.
Exit the part editor, update (this selected part only, or all if it is not also used in another instance)
Hope this helps.

All this "smart" functionality really p....s me off. Nice if you want clean easy to read schematics, but a disaster if you are dealing with multiple supply voltages or voltage sources that runs through decoupling networks.

My advice: Edit the schematic symbol. Make the power pins visible and make manual connection to their respective supply voltage.

Then after finalizing the schematic, make a netlist using "Wirelist.DLL" and do a manual check of all connections.

This can save you troublesome board spins.
