Niagara not affect by actor's CustomTimeDilation?

When using the old ParticleSystem, when attaching the ParticleSystem to a character, the ParticleSystem’s playback speed is affected by the character’s CustomTimeDilation, but when Niagara is attached to a character, it’s not affected by the character’s CustomTimeDilation…is there any way to make Niagara affected by the character’s CustomTimeDilation?
