That is fine for generating BOMs, but the Pick & Place files are
generated from PCB, which only has the RefDes, Description (footprint
name), and Value available. Placing a DNP in the value field will at
least propagate through to the PCB layout.

One the point of info available in PCB, is it possible to pass any
other attributes across when using gsch2pcb, or substitute other
attributes for the Description or Value? If you could pass a different
value for the description, like DNP or a stock code that could be
useful.
