Adding custom properties From DT

Hey guys,

Im wondering if anybody knows how to add custom properties to a part from the design table?

Im working in the assembly level using Top-Down Modeling.  Is there anyway using api or a DT to assign custom properties at the part level from the assembly DT?

If not, lets just say that I have a part DT and I want the DT to input all of my Custom Properties.  How would I go about this?
