Sometimes it is preferable to contain information within a callout, rather than a heading. If the note is mature and there are multiple lines already contained under a heading, i.e, a bulleted list, it could be slow to make the change.
Proposed solution
Add a command to convert a selected heading and the text beneath it into a callout. In lieu of selected text, all content beneath a heading until the next heading is included.
Select heading and desired content it contains
Execute command
Callout is created with the heading as the title and the content included in the body
Current workaround (optional)
Search and replace if a bulleted list is used (i.e., replace - with > -
