It should include the option to filter contacts created by Form, Inbound Call or SMS.

Would love this as a column too Core Platform

We want to see which ones are created by Zapier, by API, by user etc. to better track down issues with specific sources of leads coming into the system

Not just User but also Typable string (ie INTERGRATION) our API or other weird ways I've seen, like Zapier , sms incoming, A pull down of users which I see, but something we can type too please

I'm looking for this functionality. I want to be able to filter contacts by whom (user/agent) created.
