Learning Plans

Hello all, looking for ways to organize my learning plans. We have multiple roles following multiple paths. Would like to see some way to organize such as:

• curriculum 1
  • section 1
    • module 1
      • sub module 1
      • sub module 1
    • module 2
      • etc
      • etc

The current system doesnt allow to set up a curriculum and then divide it without creating seperate learning plans for each section. Thanks in advance for your comments
