Making a PaperZD Character. How do I lock the rotation for specific axes?

Hey there, I’m fairly new to UE engine, but I had a game idea that uses PaperZD. I basically need to be able to have beat 'em up styled camera/player movement (with the sprite always turned towards the camera). My character is able to move left and right, flipping the sprite and facing the camera.

WorkingLeft

(input right)
WorkingRight

However, when the character moves towards the foreground or background, the sprite rotates towards that direction.

Is there a way to make sure the character can move left, right, back, and forth, but their sprite stays angled properly?

I have a very simple blueprint so far for movement:
Character Blueprint

I have also messed with a few settings for the character (added spring arm to camera and such) if that information helps.

I appreciate any and all advice, please and thank you!
