Both of those requests need deep customization of the code which is outside of our support scope. You will need to hire a developer to create the feature for yourself.
The help that we can offer is to show the place that the breadcrumbs are generated. Go to:
and copy the
x_breadcrumbs function to the functions.php file of your Child Theme. Now you or your developer will be able to safely do the changes to the Breadcrumbs code without changing the core of the theme.
