How to re-send a JETI email with same content as previously sent email

Hello team, I am working with a client to re-send email notifications from the Emails tab of the JIRA issue detail screen. The emails are sent with custom templates we have defined for the client's business. When I click the Reply, Reply All, or Forward buttons for an email that has been sent previously, there is only one item available in the Email Template drop down box - "Default." None of our custom templates appear in the Email Template list.

How may I configure JETI to either 1) Display the full list of email templates we have defined in the Email Template field on the Reply/Forward screen, and 2) Ideally, to have the same template that was previously used to send this email to be automatically selected rather than have the user select the template, which is an error-prone operation.

Thanks,
