macro to change a certain property value

Hi.

I want to make a macro that makes a certain property equal to another...

I have a peoperty called "PART NAME" and another one called "Description". 

all I need is to be able to give description the value \$PRP:"PART NAME".

Oh and if it was possible to have that done to a batch of files it was great....
