Is there a way to add leading zeros to the generated JIRA issue number

[Jeannine Hooper-Yan]

Is there a way to add leading zeros to the generated issue number so we can get a numeric sort over the text field?  Example:  PRJ-0001 instead of PRJ-1

If you just want to sort it correctly then it is important to note that the JQL:

order by key

Will work on numerical ordering as expected.

No.  You would need to rewrite a load of the core code to do it, and quite probably, some of the add-ons.
