[Elecraft] K3 Feature Suggestion (CW)

[Radio Amateur N5GE]

I use CW almost exclusively.

When I'm on 6m up, working weak signal, I send CQ in CW while the rig
is set to USB.  In the CW memories M1, M2, M3 and M4, I have messages
stored for calling CQ, etc., but when the mode is set to USB and I tap
one of the memories, naturally I get a memory saying the DVR is not
installed, which is correct.  

How much trouble would it be to do an if/else check for the DVR and if
it isn't present, send the CW memory?

It's not a show stopper, but would be nice to have for those of us who
may never install the DVR.  Or perhaps setting a software switch that
would let us choose which memories we want to send from?

Not a show stopper, just a thought.
