I don't know but would this help?
I guess Im not exactly understanding . . .
Burial date and place is an option to enter into Familysearch.
like here is the entry for my father
you will see a burial location has been added.
you can navigate through your tree and see which entries have a burial location cited.
you will often see matches with Findagrave entries also.
but im not sure we are understanding what your precise question or desire is.
It sounds like cyates would like to be able to produce a list of all the people on their "following" list that are buried in a given cemetery, so if they happen to be taking a trip somewhere, they could have such a list handy to go and find those headstones.
This same type of question has come up a couple of times before.
The Search Family Tree function does not allow you to specify burial locations and you can't limit the search to just sections of the FSFT either.
However, if you have been backing up all of the work you do in the FSFT into a local database such as Ancestral Quest or RootsMagic, then it is a cinch to simply take your list of all persons and sort it based on burial location.
