Unfortunately the program is in large memory model with code in multiple segments.

It seems as if all symbols that have the same segment in the EXE file end up with the same segment in RAM, but not sure if that is by design or just how it happened to be? I used that to find one function after locating another function that had the same segment in the MAP file. But that was a bit time-consuming.
