I have recently inherited a large Confluence project and to my dismay, I have found a significant amount of duplicated content with random edits that has resulted in inconsistent content.
For instance, there are many notes and alerts as well as paragraphs that I would like to reduce down to a single source copy of each.
Rather than arbitrarily selecting a page to host the master/source copy, I am thinking of creating a "hidden" section dedicated to hosting each source note. In MadCap Flare terminology, I would call these "Snippets". Then use the Excerpt macro - Excerpt Include or Include Page macros to add the notes to each page, where required.
In the absence of any respectable content reuse functionality, is this a good practice?
I'm a novice with Confluence so please be gentle. 
Thank you for your advice.
