Adjusting player pitch automatically

I want to make it so that when I hit a face button on the controller, the player smoothly looks down at the floor and then when I press a different face button, they look back up to the default height (straight ahead). Basically just increasing and decreasing the pitch values every tick until they reach certain points.

Could someone be kind enough to provide a blueprint screen cap of this process for me?

Thanks in advance for any help.
