How can I prevent one donor from receiving the 'subsequent sustaining gift' autoresponder?

AllisonCosta

I entered an offline sustaining gift for a donor and she received the initial thank you autoresponder.  Now I need to prevent her from receiving the subsequent monthly thank you autoresponders.  Is that possible?  I want her to still be able to receive all other types of autoresponders and mail just not the monthly thank you.

Any help is greatly appreciated!

Thanks
