Newbie - automating decision practices

I am evaluating OJS for use on a set of journals and I like almost everything I see, with the exception of automation of acceptace practices. We have journals that accept an article in a number of different ways:

  1. The chief-editor is able to accept
  2. Any editor is able to accept
  3. By recommendation of one editor and acceptance of chief-editor
  4. By majority vote of the editorial board
  5. By unanimous vote of the editorial board

just to name a few.

I would like to have that automated and properly recorded. I searched for plugins on similar work and did not find anything close. Is there a directory to search for independently developed plugins? Has anyone heard of anything close?

Many thanks!
