Forward to PCB property does not exist

Referencing the recently updated MG547284 I set out to exclude from passing on to the net list a bunch of documentation items that we need to have on our parts lists.

First problem encountered was the property Forward to PCB does not exist. Not to be deterred I fired up the Property Definition Editor and noted it was not there either.

I added a User property Forward to PCB True|False and applied it to the documentation items, but the items still get passed to the netlist / PCB.

What am I missing?
