User defined Function blocks and Faceplates in Yokogawa CentumVP DCS?

We have Yokogawa Centum VP R4.02 version running on Windows Vista.

I want to make user defined Function blocks (e.g. Add on Instruction/Program) and then link these Function blocks with user defined Faceplates as ABB 800xA DCS allows.

So question is if Yokogawa DCS offers this custom user defined Function Blocks and Faceplates if yes then please guide me?
