Acquisition Date: Best way to reference SF Created Date

We have some BDMs who are adding new leads to SalesForce.  In SalesForce, we are adding them to a specific Campaign and I have a smart campaign that will add the Acquisition Program.

I am trying to add an Acquisition Date and I would like to reference the SalesForce Created Date as the Acquisition Date.  Is there a token that I can use in the "Change Data Value" to reference the Created Date?

Thank you
