Customize action of existing provider

[circld]

Is there a way to customize the action of an existing provider? Concretely, I personally find bcommits much more useful when hitting enter opens a diff comparing the latest file to the commit in question:

I've made this change in-place, but i recognize that this is not ideal. I can certainly copy the entire provider as a new custom provider, but that seems heavy handed for such a limited change.

Is that my only recourse, or do I have other options here?

You can override the existing provider in your vimrc like this:

  let g:MyBcommits = g:clap#provider#bcommits#

  function! g:MyBcommits.sink(line) abort
    echom 'New Sink'
  endfunction

Awesome, I knew there was a better way to accomplish this.
