Is there a way to modify default parameters for face, limb IK, walk and eye gaze behaviours ?

Hi there ! 

I've been using Character Animator for a year and a half, animated over 150 Youtube shorts and more than an hour and a half of full animation via Character Animator. With all that time spent on Ch, I now know how to proceed whenever I want a new character to be rigged, and that implies changing a few parameters on the properties panel each time I import a new one.

For instance, I don't like the "Head Scale Strenght" nor the "Parallax Streght".

I don't use the Eye Gaze behaviour via the camera, but only through the keyboard arrows.

Same goes for some other behaviour : I change the "Bend Strenght" down to 60% on the Limb IK behaviour, and always put the "Strenght" of the walk behaviour down to 70%.

I could be fine with doing these modifications each time if I had very few characters I need to rig for every new projects, but since I have a lot of them (more than 1500 .ai files on my computer), it is really time consuming.

Is there any way to change the default parameters ?

Thanks in advance !
