I think using "define symbol" may be appropriate. I have tested the
following, and it works with a netcdf file/variable of mine.  You can
define each region as a string that will be substituted in the plot
command, as follows:

DEFINE SYMBOL POHNPEI = x=158.00E/y=06.875N



ought to do the trick. I'd be surprised if there were a limitation on the
number of symbols you can define, but I don't know.

Good luck,
