So now I gotta bust out the snagit for you on a production system...cause you done called me a liar 
Here's your screenshot for ICMP Path Jitter
Now you are also saying they don't have Path Echo....here's that screen too
You are correct about the ICMP Jitter that function isn't currently supported. Meanwhile, I didn't find any other commercial software that currently does support that operation so I think that one is a decent one to add.
