Option to turn off email notifications for idea creators originating from Zendesk tickets Merged

We are using the zendesk integration and track feature requests via creating ideas from within zendesk and creating them in Aha.

The submitter of the ticket from Zendesk receives and email that the idea was submitted / created. We would like to be able to turn off this functionality so that the Zendesk ticket creator doesn't become the idea creator and a subscriber. We just want to track it internally.
