Not that hard to make yourself... Run this in your Rest() of your class. Lua.DoString("RunMacroText(\"MACRO\")"); Where MACRO is your macro to craft the Heavy Borean Leather.... You should find some crafting macro's in the forums.
It only makes "Borean Leather" from "Borean Leather Scraps" , you need leatherworking for "Heavy Borean Leather". But i agree with metus, it's totally do-able from within the CC.
