add third column on product page

I’m having an issue on the single product page to add in a second sidebar that is used on the rest of my theme.

I’m not sure where or how to make it work.

In single-product.php – there is

do_action( ‘woocommerce_sidebar’ );

but that is only for one of the sidebars in my theme – I also need the second one.

Suggestions?
