Add a new mailing address to Eloqua with Multibranding

Greetings, community!

We need to add a new email sending address to our Eloqua instance.

The instance has multibranding, but reviewing the official documentation, we can't find the correct way to add the address.

We have the following questions that we haven't been able to clarify with the documentation:

1. The proper process for adding this address.

2. Implications of the number of addresses and configuration requirements according to the package the client has purchased.

3. Other pertinent considerations to take into account.

We appreciate any information or guidance you can provide.
