Redhat Satellite 6.2: How to isolate contents for specific capsules

Let’s think a Satellite infrastructure as follow:

1x satelite core
multiple capsules ( 4x, 6x, or more )

What if we need to host custom packages isolating them on a single or only two capsules?
Satellite 6.2.x does not have this feature natively. In my case I solved with these steps:

1) Creating a new organization
2) Creating a new capsules inside the new organization
3) Modifying the subscription manifest and assigning a new one on the new organization

With this I’m sure that contents on the new organization are isolated between those capsules. I tried everything playing with Lifecycles/Content Views, but I was unable to isolate the contents within the present organization.
