Parent portfolio page link in breadcrumbs

When you stay on a single portfolio page and click on the Portfolio link in the breadcrumbs, you are redirected to the portfolio archive page by default.

If you want to be redirected to a custom portfolio page, there is a workaround for this. All you have to do is to follow the next steps:

1. Install and activate Polo child theme. It is required step, since all custom changes must be implemented in the child theme in order to keep them after the next updating.
2. Open .../polo-child/functions.php file in Notepad++ or other editor.
3. Copy/paste the function that you find here.
4. Upon copying the code, change '/portfolio/' slug to the slug of the required page.
   
5. Save changes and check the result.
