What you have described is the SITD foot!
Silly PuppyMommy!! 
Me too, use the AccuFeed with the SITD foot! .... and before I had that, walking foot. There is a SITD regular foot you can get, but if you are doing anything of any size, you definitely want your walking foot (or accufeed) on.
CoffeeBreak ... your problem re being "in" the ditch ... move your needle til you get it riding right where you want it to be. Before I start SITD, I spend quite a bit of time with samples to get it set to exactly where I want it to ride and that little plough, steers me right along!
It's not that you can't do SITD via FMQ ... after all, that's the way our LA'ers do it on their machines.
Just like regular FMQ ... to FMQ SITD .... practice practice practice!
