I used the preset Quick Explode (Is it a preset?), and after a while, I wanted to change it so Quick Explode happened later on in the animation so I could animate before it (like you would on the dope sheet), but I couldn't find out how to. If anybody could help that would be AWESOME! (P.S. I'm using cell fracture if that makes a difference) Thank you for your time.
To change this, go to particle system settings and change the start and end frames to the desired frame.
