Ok so I figured it out, although @Adamixoye you probably know this already.
You are correct in stating that midi designer movements will not move the parameters in the FI editor. However, it does work the other way. Basically I created a knob in midi designer, pressed "learn", and moved the appropriate parameter in the FI editor I wanted it to control. Then when I move the slider in the FI editor, it moves the knob in midi designer. Very cool. Perhaps this is a basic function or knowledge to all you midi designer folk, but I'm a newbie with this midi designer stuff so it's kinda exciting to me! LOL!
