[MothurGUI tool] parameter specification

Hi,

Is it possible to sepcify the number range for the number-options in the mothurGUI-file?
It would be nice to know the boundaries f.E.

processors=1

better for a ui-tool would be

processors=1/0/?/1

For startvalue = 1, minvalue = 0, maxvalue = unbound( ? ), step = 1.
If we know those parameters it would be easy to create a
JSpinner for the number options.

Regards,

TL
