Yes.
ModulateSpeed( e, < speed> )
SetAnimationSpeed( e, <speed> )
I think the first one modulates the movement speed so you probably only need the second for a static character.
A speed of 1 is normal time (i.e. whatever the animation speed is in the fpe or wherever it is set), 0.5 would be half speed, 2 would be twice etc.
Been there, done that, got all the T-Shirts!
