[Elecraft] K3 Undo/Back Button..?

[Edward Dickinson, III]

I wonder if the K3 knows it's own state at a given moment and can (could be
programmed to) remember it after a change of state.  Is it possible to
create a stack with the last 8/16/32 changes to the state of the K3?    

If so, a Button function for Undo/Back/Go Back could be useful. 

TAP to Undo the last [Frequency Change/Band Change/Mode Change/Setting,
etc.].  ...another TAP to Undo the previous change, etc.  ...HOLD to redo.


Best regards,
