Best Practice for custom functions in child theme

Hi there,

I am using the Child Theme for customizations. However, if I want to add new page types with custom functions to the Child theme, I want to store the custom-function.php in the Child Theme directory, not the Aegaeus functions folder.

Right now, you load functions with:
define ( ‘HBTHEMES_FUNCTIONS’ , get_template_directory() . ‘/functions’ );

How would you load functions from the child theme?

I would like something like:
define ( ‘HBTHEMES_CHILD_FUNCTIONS’, get_template_child_directory() . ‘/functions’):

I want to do this so when I update the theme I can delete everything and upload easily without worrying about deleting files.

Thank you!
