RS5k manager: Macro | Using real values for link range instead of percentages

[IOphonics]

Since the Macro has to know about the parameter ranges of its slaves anyway, can't we use those real values for the 'Min' and 'Max' fields in the link list?
It would be really handy to explicitly say for example that you want the pitch range to be between -12 and +3 semitones instead of trying to translate that experimentally to the percantage scale.
