Adobe FrameMaker and MadCap Flare have variable features that allow you to reuse content (as you can in Confluence with the Excerpt, Excerpt Include, and Include Page macros) and have such things such as product names and release versions change to match the current project.
Is there anything available like that for Confluence? I'd expect K15t's Scroll Versions to have that feature, but I can't find it in their documentation.
Atlassian's template variables are a different feature. What I'm looking for is covered by https://jira.atlassian.com/browse/CONF-3999.
