Hi guys
Thanks for the topic and ideas.
I’ve just added in a new action (to the next version not yet released 5.2.6):
‘acf/render_field_group_settings’
You will be able to use it like this:
add_action('acf/render_field_group_settings', 'my_function', 10, 1);
function my_function( $field_group ) {
}
