Adding new lead data in a field without erasing the existing one

[denissemiranda]

Hi guys, 

I am trying to add a field that keeps historic information and can be exported in a CSV when I export it from the contact/lead section, so it has to be Lead Custom Field.

Is there a way to set up the Data Change trigger or the flow like something "{{lead.CustomField}} + {{lead.New.CustomField}} to keep old data but add new one? 

Thank you for your help.

Yes, you can create a custom History field in which you append the value when a value in the original field changes (or a new person is created with a non-empty value in the field). Check out the below campaign setup:

Flow:

Set the campaign qualification rules to allow people to flow through the campaign multiple times. I hope this answers your question.
