How do I make slow down of objects for certain time?

I've got enemies spawning and sometime there's a slow down power up that can be used to slow down enemies. The ones that are already in the layout slow down but the ones coming into the layout move at normal time scale. How do I make the slow down time for a certain duration on all enemies that that have yet to enter the layout as well?

Hey Usman, I think I got it working the way you asked,
