Only because M2 is too lazy to bother. Any controller capable of
RS-232 input should have more than enough processor processor power
to support point and shoot operation if that feature had been part
of the initial design. Unfortunately, an aftermarket modification
would require essentially a complete rewrite of the controller
firmware to support a potentiometer input.
One alternative to the Green Heron might be the pulse version of
the MDS controller:

It's not exactly inexpensive but it is half the cost of the Green
Heron depending on options.
