Feature Request: Smart Substitution of Workout w/ Z2 Ride

Two parts/possibilities:

  1. Rank each weekly workout in terms of priority (to be prominently displayed somewhere), so if I want to replace one with an endurance ride, I know which is the least important.

  2. An automatic “replace with Z2” option in each workout, sort of similar to Train Now, but for an existing planned workout. Would also be great to have this built into Plan Builder, i.e. “tell us how many days/week of intensity you want."
