PF1e some of the "core" sources are not available

[evilsquid55555]

Is your feature request related to a problem? Please describe.
Our group uses what we know of as the PF1e "Core" rulebooks. This includes all of the Paizo published rulebooks that are not Adventure Paths, Player Companions, or Setting Sourcebooks.

The vast majority of these are already available, but these works are missing:

• Book of the Damned PZO1139 - be warned, the content is "almost" the same as that which is presented in PZO9213, PZO9225, and PZO9239. There are noticeable variations in the Prestige Classes, so it is likely that there are some variances in other content as well.
• Planar Adventures PZO1141
• Villain Codex PZO1136

Describe the solution you'd like
Quite simply, our group would like to be able to use PCGen with access to all of these core rulebooks.

Describe alternatives you've considered
I personally am mainly interested in the "spiked chain" feats from Book of the Damned... I tried to implement them myself in a homebrew but failed so very badly

Additional context
Thank you for all the work
