Deactivating and Reactivating 8direction's Angle

Alright its probably very unkind to come asking before even introducing myself ,but here it goes:

how do i deactivate the "set angle" in a similar maner to deactiving acceleration (instead of doin it by deactivating it on the behaviors tab itself and placing an event to tell it where it should look),

and how do i activate it back just the way it is by defalt (looking to the direction its headed smoothly)?(the bit in bolt is the most inportant sinse i can aread deactibate it in others ways)

i just realised i can get a similar effect by pinning sprite i want on top of the hitbox sprite that will be featuring the 8direction behavior and making the graphic animation itself turn...

still the question stands.
