Change title of Confluence Administrator's guide

From customer suggestion received:

I'd like to suggest that you change the title of this page, https://confluence.atlassian.com/doc/confluence-administrator-s-guide-138143.html, from "Confluence Administrator's Guide" to "Confluence System Administrator's Guide."
It's confusing because there are two levels of site-wide admin: System Administrator and Confluence Administrator, as described at https://confluence.atlassian.com/doc/global-permissions-overview-138709.html
A response is not necessary, but I would strongly recommend the change because words matter, especially for new users.
