Batch Merge - how to 'keep' all emails
Some duplicates are caused by same name, different email.
When merging manually, there's an option to add email from the duplicate contact, ie keep both.
When batch merging, there doesn't appear to be an option to do that, and the duplicate email is 'lost'. How can this be addressed either by configuration or workaround? a) change the configuration of bulk merge to keep all emails? b) manually exporting dupes and reimporting the duplicated email? c) a custom extension / database operation?
