[Feature Request] Add Options to "Keep X episodes" Feature

I would like to suggest that the options available in the “Keep X Episodes” feature be expanded slightly to give users a bit more control over how many shows are retained.

The options that I’d suggest adding are:

  • 2 episodes
  • Episodes from the past 2 days
  • 4 episodes
  • Episodes from the past 4 days

I realize the list could get very long if every possible option was added but I think it’s reasonable to have more of the lower-number options available as these (I think) would be more likely to be used by people. For example, I have a number of shows (talk shows typically) that I only want to keep for the last two days / two episodes.
