Workout Mode - Power Range Interval

I’d like to see a power range interval type added to the workout mode where the trainer power is maintained within a range, say 45%-65% of FTP.  As long as you’re in that range the trainer resistance follows the contours of the road.  If you drop below or go above the range then erg mode kicks in to maintain power.  It seems like this could be accomplished by widening the power hysteresis band, which is presumably used currently.

<Range Duration=“600” PowerLow=“0.45” PowerHigh=“0.65”/>
