How do you change Delay units in Logic Pro X

I think I've solved my own question. To synchronize the wave signals of spot microphones which need to be delayed to match up with the room microphones sound waves, I'm going to use the nudge short cut and change the units to ticks.

Much appreciated Edgar. This has really helped with more precise nudging of tracks.

I am trying to synchronize 3 paired microphones to minimize phase issues – two sets of stereo spot microphones and one room microphone farther away. Do you happen to know if there is an automated way of synchronizing regions in Logic Pro. I know there is is Final Cut Pro.

If not, it would speed up workflows immensely if Logic automated synchronization. Even when I boost the gain in the file editor (and then undo the post later) to more clearly see the audio waves, it is very difficult to synchronize tracks manually.
