Create additional issues
If your JEMH version is recent you should have a method on jemhUtils to create a new result set, within which additional parameters can be set, to drive issue creation (or possibly update!)
See Script Context for a link to jemhUtils, if the following is present, it can be used:
Here is the script showing how a new 'result' is created, and added to.
// create the main issue
resultMap.put("labels", "hello-world");
resultMap.put("project", "TEST");
resultMap.put("priority", "medium");
resultMap.put("issueType", "task");
resultMap.put("summary", subject);
resultMap.put("comment", body);
// create a duplicate
var secondResult = jemhUtils.createResultSet();
secondResult.put("labels", "duplicated");
secondResult.put("project", "SCRUM");
secondResult.put("priority", "high");
secondResult.put("issueType", "bug");
secondResult.put("summary", 'DUPE: '+subject);
secondResult.put("comment", 'DUPLICATE ISSUE\n'+body);
