I am trying to update a picklist field on Contact with the Stage Value of an Opportunity. We have a Contact lookup field on Opportunity, but I am unable to get to the field in question via Process Builder. Is there a way to accomplish this declaratively? (I can see other Contact fields, but not this one.)

Our use case: we use a specific Opportunity Record Type to track applications. We want to update the value of a Picklist field on Contact so that the value in that field matches the most recent application.

Thanks in advance!
