Resend of Issue to Assignee

Hello,

I would like to build a list of 'issues' and when I am ready, send a notification email to the assignee. Is that possible? Can I pull the trigger to email an issue to an assignee as needed ?

Alternatively, is there a way to 'resend' the email that was initially sent when the issue was created. I could just disconnect my client wireless when I create the issue and 'resend' it later using that method.
