Issue with locking the Smpte-position

Hello there,

I just decided to switch back on my beloved Cubase, after being forced by my university to use logic for a while.
Over all it’s really great, but I have one issue I can’t solve at my own.
How am I able to lock the smpte positions of my cue’s while working on a film?
In Logic, it was really easy. There is a simple function that is called “lock smpte pos.”
So, when you export a smpte-locked cue as an audio file and import it back to the main-project,
the cue will be just at the right position.
I’ve been looking for this function for a while now but couldn’t find any appropriate solution.
Also Google hadn’t had the right answer to me.
