[Elecraft] RIT behavior when computer controlled / Possible Feature Request

Hello,

I'm curious if RIT on the KX3 should behave the way it does when under
computer control. (CAT commands.)

As a basis for comparison, this workflow does exactly what I would expect.

1. Tune to a CW transmit frequency.
2. Press and hold the [OFS/VFO B] button to clear RIT.
3. Press the [RIT] button to enable RIT.
4. Call CQ, operator responds off frequency.
5. Adjust the [OFS/VFO B] button to get the receive frequency close.
6. Press the [SPOT] button to zero in on the precise receive frequency.  

(Transmit frequency remains as it was originally.)

Steps 5 and 6 work fine, although precious seconds are gone during this
process, and, depending on how close I get with step 5 (and the filter
setting), the SPOT could hunt for additional seconds.  During the SPOT
process, the RIT offset adjustments are continuously displayed in the VFO B
screen area.  This works, but is time-inefficient.  (I will probably miss
their call sign.)

My particular (preferred) scenario:

I am 100% a CW operator. I use CW Skimmer, basically as my panadapter. CW
Skimmer, using CAT commands, can snap the KX3 to a precise receive frequency
with a mouse click. (Basically the same effect as SPOT, but quicker.)

Assume that steps 1 through 4 are the same as above.  Instead of steps 5 and
6, I would like to be able to click on a the operator's off-frequency
response within CW Skimmer and have the KX3 behave the same as the [SPOT]
button. After all, they are essentially the same thing, one just happens to
be driven remotely (CAT Command), the other using a local button press (SPOT
button).  However, the KX3 changes the receive frequency, but does not
adjust the RIT offset.  So what that means is the new receive frequency is
now the transmit frequency.  Not what I would expect with RIT in effect.

Is there a setting to get the behavior that I want?  If not, I would like to
kindly put in an enhancement request.

73,
