[Elecraft] K3 Amp Key configuration request

I use my K3 with an Ameritron ALS-600 amplifier and MFJ-998 autotuner (hey, 
the KPA-500 and KAT-500 aren't available yet).  Anyway, I tune the MFJ-998 
by leaving it in the full auto position and then just press TUNE on the K3. 
I set my K3 TUNE power for 15 watts which is a perfect level for the 
MFJ-998.  However, the amp enable line on the K3 goes low even when using 
TUNE, and so I must remember to place the amp in standby before checking and 
tuning SWR.  Otherwise the amp will put out power momentarily (60-100 watts) 
until the MFJ-998 interrupts the amp-key line if it needs to tune.  It would 
be nice if the amp-enable output of the K3 would not go low when using TUNE 
on the K3.  Maybe a menu set-up option?
