Rules to award badges needs to be more refined

Ideally, there should be a way to define multiple rules for the awarding of a badge. For instance…

• Rule 1: you must complete all of these activities (select multiple).

• Rule 2: you must complete at least one of these activities (select multiple).

• Rule 3: you must have already achieved these badges (select multiple).

This would allow stacking of badges and more refined criteria and the current system doesn’t work for these scenarios.
