Buying/Adding Bestiary Weaponry to PCs?

[Shokotsu]

So, I am currently playing through an Extinction Curse campaign and have acquired a Rhoka Sword. I went to add it to my sheet, but found the bestiary weaponry to be missing. I manually created the weapon, but I was wondering if there were plans to add the weapons and such from those books? Also, I currently own all of the Pathfinder 2e books on Hero Labs Online (including the Bestiary books). Thanks for the time of whomever may address this.
