For example both Deployteq IDs 00000001 and 00000002 have the email address email@gmail.com. I want merge them to one ID and keep 0001's firstname and surname, and 0002's job title. Etc.
In Constant Contact (Sharpspring) this is possible (https://knowledgebase.constantcontact.com/lead-gen-crm/articles/KnowledgeBase/50399-Merging-Contacts?lang=en_US#h_143376956101519680999032)

Merging individual customer records is not something we are currently considering to implement. We already offer the possibility of deduplicating the whole database and provide features that prevent duplicates. Thanks for the feedback!
