Years Old LiveTrace Issue

It's entirely possible I am missing something but there has been an issue with LiveTrace for years that I hope will be addressed.

I have a gigantic Wacom Cintiq that I use as much as I can, but oftentimes for cartoon work I get better results with good old pen and paper. I scan in the black line work, LiveTrace, and add color on layers below with the Wacom. I do apologize to the trees I've brought down but it is how I get stuff done.

Back in the CS5 days, I could import multiple scans, select them all, and LiveTrace would apply the same settings to all of them. Makes sense to me. Same pen, paper, scanner, and drawn at the same scale. Simple black line art that LiveTrace can sort out pretty easily.

Nowadays I have to LiveTrace each individual scan individually. It isn't possible as far as I can tell to LiveTrace multiple images at once. This can be really tedious when I'm scanning in multiple frames for animation or something similar. Illustrator also still warns me that "Tracing May Proceed Slowly With This Large Image" but it just is not slow. Even back in CS5 it wasn't that slow, now on my full blow work rig the LiveTrace is done long before I could close the warning box.

So, am I missing something? Or, couldn't there please be a way to LiveTrace multiple scans again?
