Cutting and pasting within a single track

As you may know from my other posts, I'm a newbie to Logic Pro. I am using Login Pro X. I have a project with two tracks: one guitar and one vocals. The each track was records in one take. So as I understanding, the tack is on "region"?

I thought I did a real good job, but while I was mixing, I blew bars/measure 44 and 45 in the guitar track. Lucky for me, it is the exact same riff as measures 42 and 43. So what I would like to do is to replace measure 44-45 with a copy of 42-43.

After much manual reading, googlinh, and youtube wtaching, I think this is what I have to do:

1. Since track 1 is one region, I need to split is up into 4 regions: 1-41, 42-43, 44-45, 46-end

2. Delete region 3 (44-45)

3. Copy region 2 (42-43)

4. Cycle it (Command-R) or move the playback head to bar 44 and paste.

First of all, is this correct? I seems like there should be a better / easier / faster way to do this?

I think I can do this in what used to be called the Wave Editor, but not sure if it will "snap" to the start of the measure correctly.

Thanks,

Kory
