Customize customizer in child theme

Great theme!

Is it possible to make changes to the customizer file in a child theme? I’d like to add a photo, name and company name to the Jumbo Headline section, but I’m not sure how to overwrite te customizer.php file.

I would also like to be able to use the Jumbo Headline on more pages (with different photo’s, headlines, names and company names).

Is this possible or should I remove the Jumbo headlines all together and add extra fields?

Thanks!

Erik
