Possibility to se all customers on same Subscription Plan

Possibility to se all customers on same Subscription Plan

We need the ability to see/list all the customers subscribing to a Plan.

This could be achieved by:
a) In Reports - Subscription Details: Make it possible to sort order by "Plan name"

or

b) In Reports -  Active Customers: Make the "Plan name" clickable, and then list all the customers on this Plan 

Is this possible, or are there any other way I can easily list all customers subscribing to a specific plan?
