[Elecraft] (K3/K3S). Eliminate the 4 sec diddle with FSK-D and KY commands using n1mm??

[Nr4c]

I'm trying to set up n1mm for the RTTY contest. I'm attempting to use KY commands and all is well except I can't get rid of the annoying 4 seconds of trailing fiddles at the end. 

Yes, I've tried adding a {RX} at the end, I've tried every iteration of the "|" as is used in the K3 memories. I think this has potential but have to solve this problem. I won't be too popular this weekend if I'm adding this artifact to every transmission. 

Any chance of making this a toggle so we can by-pass it in config?  I assume it's there for "paddlers" to have a short pause time or not stopping and starting so much for slow code. But even a 1 second hold would make this tolerable. 
Help!
