You can copy and paste without having to recheck the octave of the first pitch you paste.
To avoid the copy-and-paste problem and finding yourself in the wrong octave too much, I have the habit of starting each part (or section or page) with a reference to the absolute pitch I am at that point. That corrects the code at least at that point and more, it tells you with an error-message that the flow of relative coded music doesn't add up correctly.
