You can’t alter the “Show on Page” or the location of the field group this way.
You would need to:
1) Create a different field group for each template
2) If you’re using ACF5 Pro you could create a different field group for each template and use the new clone field to duplicate the fields
3) Again, in ACF 5, there is a hook acf/get_field_group and you can add a filter to filter the field group when it is loaded.
add_filter('acf/get_field_group', 'my_get_field_group_filter');
function my_field_group_filter($field_group) {
// modify group settings
return $field_group;
}
Inside the filter you might be able to detect what page is being loaded and alter the group settings based on the page template. I am not 100% sure of this last option or the details on what you’d need to do here, it’s just a guess on my part. This filter may run before you can figure out what you need.
