Find and Merge Duplicate Deals

I know we have this function for accounts and contacts, but I can't find it for deals, as I would like to avoid having any duplicates. Thanks

Moderation update:

We are happy to inform you the support for managing duplicates in the Deals and custom modules in the CRM. You can now manage duplicates in these modules in addition to the Leads, Contacts, Accounts and Vendors modules.
