Can I delete an auto response for just one person?

I would like to set my form to followup with the person 24 hours after submission.  However, if they contact me, say by phone, before the autoresponder goes out, can I hold back the auto response for just that one person?  

It is not possible to stop the delayed autoresponder for a single user.  Once a delayed autoresponder is triggered to send, it is not possible to stop only that specific email from sending.
