This can be done in any order that will accomplish all three tasks: 1) solvate, 2) add one Mg2+, 3) write psf. I need to be able to specify the coordinates of the Mg2+ ion rather than having it automatically placed at a potential minima.

the psf file does not contain any coordinate information, so you would
need only one .psf file,
unless you want to remove water molecules depending on your placement
of the mg2+ ion.
