Thanks, Carolyn, that is correct.
@Taylor: We just have a category for Freemasonry at the moment. A Knight Templar is part of the York Rite, which is part of Freemasonry.
We don't have a separate category, yet, for Knight Templar (or York Rite, or Scottish Rite), mainly because currently there would be so few people in such a category.
The current recommendation is to place the profile in the "Freemasonry" category, and to detail all Masonic achievements and affiliations in the Biography of the profile.
... And lastly, I haven't created a template or badge because I'm not a WikiTree Leader, but mainly because there hasn't been many requests for it either.
