Incremental content view updates

Hi,

Currently we update our servers quarterly and in a few cases additional updates is performed in between in case of severe security issues.
We have done so by publishing new versions of our content views, but that causes all errata to be available wich might not be desired.
I have therefore looked into the "incremental content view updates" feature in Satellite described here:
https://access.redhat.com/documentation/en-us/red_hat_satellite/6.8/html/content_management_guide/managing_errata#Managing_Errata-Adding-Errata-To-An-Incremental-Content-View

I have managed to publish an incremental update to one of my content views, and assigned only one host to it for testing.
Is it possible to add additional content hosts after the incremental update has been created? Is it possible list all hosts that was included in an incremental update?

Thanks,

Erling
