Making a "NPC Toggle" like the one for the 5e OGL sheet?

Just curious how easy this is, and if it's something "copy and pastable" as that outside of a handful of mods is right about where my skill level is at. I could really use a NPC toggle for something custom I am working in, to many stats that are only ever important for PCs, and even then not that often referenced.
