Set timeline to zero for each clip

Hi,

Im completely new to Premiere Pro. I've been asked to cut up some clips and put them in order. Simple stuff. The thing is that i've got instructions on where to cut per clip. When i put them in order, its one one big timelime, obviously. Since my instructions for the clips are seperate, i don't know exactly where to cut after a while. What's the easiest way to set the timeline back to zero for each individual clip?

I hope i've made myself somewhat understandable. I also realise it's probably really easy but i couldn't find the answer and didn't know how to phrase it exactly, hence i'm asking for your help.

Thanks!
