Template part folder path

Hi,

It is possible to call files ( like header.php ) located in a sub folder? ( rather than in the main folder).

I′m using this path /wp-content/themes/my-child-theme/my-templates
to keep everything in the same place while working on a Premium child theme & make the development Update Proof.

Page templates works fine but header.php doesn’t load if it is placed in my-templates folder.
