I realize now that you asked how to find or check that a specific cemetery already has a category. This is the way I do it. I am sure someone else knows a more efficient way but until then try this.
On the dropdown menus at the top: Go to Find> Select categories.> Select Cemeteries.> Select North America (if looking for a US cemetery) > Select United States > Select the State (this case it is Tennessee) > select the County (this case Fentress) and then you get a list of all the cemeteries in Fentress county that have been categorized.
Another way which is faster but you have to know the exact name used here at Wikitree. When on the profile in edit mode, you will see a set of buttons at the top of the text box where you write the bio. The second from the right (looks like a stepdown chart) is the category button. If you click the button a box appears and type in the name of the cemetery. In this case Upchurch Cemetery should have appeared and you could select that.
I hope I have not confused you.
