Locking different parts within a track

Hi all.
I would like to know if it’s possible to “lock” different recorded parts within a track.
Like in the image, I have a basic recorded LP track over which I recorded another couple little parts. Since I have to move all the region to the right, I would like to avoid clicking the base track, then the little splits over it because it would be hard to position them again correctly.
I tried to select them all, right click and see the menu but there isn’t anything that allow this task.
Also. Should be possible to move all regions at the same time instead one at a time?
Thank you

You can select the regions, then Edit > Combine them to one “pseudo”-region. You can uncombine them later.
You can also select e.g. all the regions in the track after the timeline, look at the Edit > Select menu to find a wide choice of possibilities.
Also, to move all regions to the right, you can use the Track > Insert time menu.
Hope this helps, regards

Perfect, thank you
