After a walk, how to switch to frontal immediately without delay ? Plus bonus question

Hello everyone !

I am working with Alex puppet. When i do a positional walk to the right, once reaching the destination, he currently maintains the right profile for an additional second. I would like him to immediately return to frontal view once arriving. What setting needs to be adjusted for this ?

Bonus question : How am I able to combine a positional walk, with a left/right arrow key walk into a single video ? Do I make seperate videos and combine them later in permiere pro ? Or am i somehow able to do it with different scenes?

There's so much to learn and I'm still a beginner. Thanks for your answers!
