Tability's editor should be smart and adjust automatically the target based on what the user types in the editor.
Ex:
"Increase NPS from 50 to 75" should lead to:
  • Starting value: 50
  • Target: 75
  • Format: _number_ NPS
"Achieve a 30% growth in leads" should set the starting value to 0, the target to 30, and the format to "_number_ leads growth"
This should only happen if the outcome has the default settings.
