I created a bunch of custom fields and made them required upon creation of an issue type. I want to use these fields to aggregate and populate another custom field in a specific syntax. I am not sure if it is recommended to use the built in functionality of the "edit issue" action or try to use the JSON option.
The custom field of {{issue.Aggregate Name}} would look be automatically populated with something like this:
{{issue.Location}}::{{issue.Year}}_{{issue.Person}} with {{issue.Title}}
