To the Customers list, please add an option to filter by active Subscribers.

On the Customers list currently there are filters for:
All Customers
Active Customers
Inactive Customers
CRM Customers
Non Subscribers...

In my use case, I integrate with Zoho CRM, which contains a customer list of hundreds. Only a few customers have added subscription and it would be helpful to quickly find them to review their accounts (without having to remember them - that is already in the system!)
