[VX]CHANGE WALKING ANIMATION

This isn't something that I NEED for my game, but I thought it would be a nice effect to make my game more real. I just want your opinions on what would be the best way to change the walking animation on an event.

The walking pattern for VX goes center, right, center, left, center, and so on. I want to change the animation (for only certain events) to be left, center, right, left, center, right, like it was reading it like a book. I just want to make it so that it doesn't go back to the standing pose every other frame.

The reason I want this is so that small critters would look more real. I want my squirrels to look like real squirrels when they run, like in this animation:


So whats your opinion? Is there a way to do this inside the event? Or, should I script this (and being a not-so-great scripter, I'm more hoping that I can do this with events). Do you have any tips as to how I would do this?
