[Elecraft] Any way to automatically bypass K3 ATU when using KPA500?

[AC6JA at aol.com]

Of course the KAT500 is on order!  I placed my order over the phone  the 
first day it became available, hihi!
I just think the internal K3 ATU should not be tuned into the theoretical  
50 ohm input of the KPA500.  Aren't there internal losses through the ATU  
components that don't need to happen if the tuner is bypassed?
I "assume" a firmware change could allow the ATU status to follow the OPER  
and STBY modes like the different power levels?
Just wonder how everyone else has their K3/KPA500 set up?

Yes, I  was wondering how he was tuning with the amp on too...
Of course we just  need to sell him a KAT500!
