Identify Merged Contact
Currently, the de-duplication tool allows users to merge contacts. This is currently an irreversible merge, which is understandable as some information is lost during the merge. However, it would be great if there could be a way to identify which contacts have been merged. Perhaps by creating a 'last merged' contact property that can be filtered by or the ability to filter for 'Email address is more than one'.
I think that if users can at least identify merged contacts, they will have the option to manually unmerge the contacts by creating new records for the contacts that have merged.
