Add another text in "title-single" area

Hi,

It is possible to add another independ text in the tour page, in div class=”title-single” area before the tour name, on the top of that?
This is the area where the tour name appears, my client want to add one text that doesn’t show in the tours grid.

I am using the video demo, and I need this in the child theme so I can update and this change remains.

I guess I have to edit the content-single-tour.php file (wp-content\themes\travelwp\travel-booking), but I don’t know how I can “child” this file, and what code I have to paste to edit this with HTML <h2> simple text.

Thank you in advantage Tanet!
