How to rest save & send setting when sending an email

Hi,

When we send an email from an issue, there is the Save & Send setting which you can click on to save the recipients you've specified so that next time you want to send an email, it remembers this setting.

My question is, is there a way to reset this setting so that it defaults back to the blank setting? e.g a way to forget the save & send?

Thanks,
Andrew.
