how to create time dilation only for a bullet

Hi, i tried to play with the time dilation node and i cant find a away for it to affect only the bullet and i am also trying to make the bullet enter time dilation only when it hits a certain mesh and not on every collision the bullet has

any ideas on might i achieve this?

You can try a makeshift reducing the projectile speed when Hit the mesh.

OnComponentHit-> Get “other Comp” and Cast to the specific Mesh, if true multiply the projectile velocity to a value of <1
