Feature Request: Midi message converter to allow a range of values

The MIDI message converter is very handy but is limited to only allow converting single values of a CC message. How about making it min and max, so for example values 0 to 127 could be converted to 1 to 15. A single value could still be chosen by setting the min and max values to be the same. Also, why is it limited to only 16 conversions? Thank you for your consideration.
