Changing Breadcrumb Link

Hello,

I am using BBPress for my site’s forum, but can’t figure out how to change the breadcrumbs to our requirements. Currently as seen in the URL linked here, the default is “Home>Current Page”, however we need the breadcrumbs to show “Home>Forum Index>Sub-Forum>Current Page”.

Under BBPress Style Kit -> Breadcrumbs I have tried to enter our main forum URL as the “Home” breadcrumb so that at least the current page will connect back to the main forum page, however the breadcrumb currently goes from our website’s front page to the specific subforum.

Thank you
