Not specifically - but then I haven't looked for them.

However, you can't do that if your application requires enabling 
a menu (e.g., TX EQ), selecting a "band" (e.g., 50 Hz), reading 
the current value, issuing a number of UP/DN commands, stepping 
to the next "band", and repeating the process to set all eight 
bands of TX EQ (or RX EQ).  Any interactive process that makes 
use of a menu is likely to "blow up" if the K3 receives a command 
from another application.  

Given the current interface, I believe any attempt to remotely 
save/change anything that requires reading the display will fail 
because of the need to pause to read the display and the chance 
that another program will clash at that moment. 

I'm not passing judgment on the "efficiency" of using an external 
application just pointing out that doing some of the things that 
have been requested may be a little difficult in a "shared" model.
