How to set track starting point for CDJ 350?

Hello!

How are you guys?

Please, I need a little help here.

Is there a special way to set the Starting CUE?

Or, do I have to do something to save what I've done inside REKORDBOX?

I really don't know what to do anymore. I've tried everything, I guess.

I imagine this is pretty simple.
I also play with a USB drive a friend gave to me, and I see some tracks start at about 1:15min in, and this is what I want to able to do. Customize where my tracks start, so it is easier to mix in.

Thanks a lot.
