Just wondering if an electric valve can be put in the pipes that go to
the second floor to make it a separately controlled zone.
Thanks

You probably have to run another pipe to break off of the first floor,
otherwise the first floor would have to be calling for heat before the
second floor would get any. Not a cheap job but they do make zone valves for
steam systems

The easiest thing to do is to add thermostatically controlled steam
vents at each radiator you want to control individually.

Make sure you get appropriate for your system as one-pipe and two-pipe
systems operate differently, and make sure that you're getting the
control that fit's into the 1/8" NPT steam vent, not the larger
version which replaces the existing valve at the floor with the handle
on top (much more work to swap out).
There are versions that have a remote thermostat that can be mounted
on the wall, with the two parts connected by a short capillary tube
(no electricity), which will allow you to put the thermostat in a
better location if a direct vent replacement control would be
problematic. Also, do not put a thermostatic control on the radiator
in the room that has the existing wall thermostat - they end up
fighting.
Honeywell makes a kit that has the vent, valve and thermostatic
control. Some other manufacturers sell the parts separately. Figure
$75 to $100 per radiator.

Just curious, are you having a problem wth one particular floor
getting too hot, or not getting enough heat? Where is the T-stat
located now?

If that's his problem, it won't matter where the stat is located. The
radiator sizing is incorrect and needs to be balanced
