Autmatically calculated byes

Byes that are calculated in the same way as finals fixtures. Either standings based or Fixture result based.  So for example, in a page playoff situation (https://en.wikipedia.org/wiki/Page_playoff_system) the winner of game two qualifies automatically for the final, so has a bye in the next stage.

Very useful for our finals fixtures as in some leagues we run with more teams than we have space for on a league night so have byes during the season and also need to be able to have these automatically generated so they will go out with the reminders and save us some effort.
