We would like to standardize/harmonize the way a particular case is documented in JIRA comments - actually nothing fancy, just a panel with a specific title and background color. For now, it requires users to copy the corresponding wiki markup (like a poor man's template) from somewhere.
I know there are user macros in Confluence, but I have not seen this in JIRA.
Is there a way to simplify this, so users can use a pre-defined custom markup or user macro in JIRA?
Note that I haven't looked at JIRA plug-ins, since our need seems to be so simple that it will be difficult for me to justify any cost.
