Hi,
We're using JIRA Cloud and I'm currently setting up a Jira Service Mgmt customer portal with a Confluence space as a knowledge base behind.
In the Confluence space settings, I set up a footer note including copyright information:

Now, this displays correctly when I just navigate to the internal Confluence page as a normal Confluence user:

However, it does not display on the version of the KB page shown on the customer portal: 
Is there a way to set up an automatic copyright note in the footer for the customer portal, e.g. under or above the "Powered by Jira" message?
I tried searching for options in the forums but most people rather want to get rid of the footer generally, which is the opposite of what we want.
Thanks
