I am wanting to place a value in a Hubspot field when I import a file, in my case, Zoominfo. The idea is to be able to find all records (in this case, contacts) that were imported from that particular file at a later date in Hubspot. Has anyone done this? I thought about using the multiple file import, but am looking for another way.
If I understand correctly, your end goal is to be able to filter all contacts that come from a specific import you did in HubSpot, correct? If so, you don't need to create a custom property. What you can do is create a list (Contacts > Lists) then filter by Imports and then choose your import name from the list.
