Add Filter For Specific Clue Tiers

[StephenWolters]

Was hoping for a filter for specific clue tiers (probably a checkbox for each one).
For example I only want to be notified about Hards & Elites, I don't care about Beginners, Easies or Mediums.

I'll bump this, I would like this feature as well.
