Recently I was asked to implement a custom breadcrumb trail for all posts in 5 different custom post types on a site using the Breadcrumb NavXT plugin. The posts belonged to different categories, were in different post types and all suffered from a messy breadcrumb trail. It was desired that all of the posts had a consistent breadcrumb trail, which was:
Home > Knowledge > {{ Post Name }}
Breadcrumb NavXT has an action which runs just after the breadcrumb trail has been built, and I was able to use it to rewrite the breadrcrumb trail to suit my requirements.

Was able to use this to make my own custom breadcrumb, thank you so much!
This was a huge help to me. Thanks for sharing it!
This was indeed very very helpful for adding custom breadcrumb titles to current breadcrumbs. I also tried adding custom breadcrumb to only a few pages using code here https://wordpress.org/support/topic/insert-item-between-breadcrumb-on-specific-pages/
Thank you.
