Can I create a hierarchy of mitigation and response plan and Mitigation and Response view?

Yes, the Mitigation and Response Plans view supports hierarchies similar to how you would set up Summary and sub tasks in a Gantt Chart.
To create a subplans:

1. Create a plan. You can do this by simply typing a name into the name field, This will be the Plan
2. Under your plan, create another plan. You should now have two plans.
3. Select the second plan.
4. Click the outdent button on Structure > Outdent.

It is possible to create multiple levels.
