[Elecraft] P3: Span control logic

Hi all, especially the K3 Product Management folks:
 
I now have some time behind the combination K3-P3, It is a wonderful
combination.  Like fishing with a fishfinder! Now my neighbor has definitive
proof in writing (a screen snapshot) that he is indeed 6.5kHz wide when he
cranks up that Macho Bass to impress his buddies on 14.250 :)
 
The P3 is a wonderful addition to my station's capability, however, there is
one ergonomic detail that drives me absolutely bonkers!  I wonder if
something can be done about it, as I may not be the only one with this
issue.
 
SPAN is equivalent to WIDTH to me.  On K3, turning the WIDTH knob to the
left (counter colockwise) makes the width of the bandpass NARROWER
(smaller).  Turning the knob to the right (clockwise) makes the bandpass
WIDER.  I have always loved how this works in this radio, it is logical and
intuitive to me, from my background in video... Video Production Switchers
(Vision Mixers for the Brits among us) Key Clip controls work this way, and
my feeble mind is used to this convention after many years of mental
conditioning.  Equipment with similar controls (namely Yaesu rigs) are
backwards to me.
 
Having said that, on the P3, selecting SPAN and turning the knob to the left
(counter clockwise) makes the span NARROWER, and turning it to the right
(Clockwise) makes the span WIDER! 
 
Yes, I know... The VISUAL FEEDBACK from the K3 control matches the screen of
the P3, which is good, but the INTENT of the action on the P3 SPAN control
does not!  The WIDTH of the marker WIDENS when you turn the knob
counterclockwise, but the actual EFFECT of the action you are performing is
BACKWARDS from the visual feedback, and also backwards from the K3 control
that does the same thing!
 
Its like on a sailboat... Deflecting the rudder tiller AWAY from you turns
the nose of the boat in the OPPOSITE direction from the tiller deflection.  
 
The chosen behavior of these controls and how they interact with the action
and visual feedback is just absolutely counter intuitive to me... Any hope
that this can be made a user selectable behavior so we can all have our cake
and eat it too?
 
Thanks for considering this request.
