This selection is not available to Pathfinder Society characters
 

There are PFS chronicle boons that grant access to features that are normally not available to Pathfinder Society characters. Is there a way to use the "Adjust" tab to enable a selection that a boon allows this way, so that you don't get a validation error for choosing a normally unavailable choice?

Install the Community Pack. Turn on "ShadowChemosh Adjustments". Go to the Adjust tab and you will find several new "PFS" based adjustments that allow making invalid choices valid.

Perfect; thanks!
