This restriction on the coordinate system being a metre grid is only for
the *output* coordinate system.

You can use `LONG-LAT` (or pretty much any other coordinate system -
the only restriction is really that PROJ supports it) as the *input*
coordinate system which is used for fixed points, and Survex will
convert them to the output coordinate system for you.
