No, and you would never want to as there are enormous benefits in consolidating agency vendors to single platform, with a single set of terms and single invoicer. You gain control and visibility and improve your workflow and communication with all agencies.
Furthermore, you will eliminate administrative hassles and never have a conflict over ownership. If agencies are used off the platform inevitably, over time, there will be a dual ownership claim and two fees owed. That will never happen with full adoption of RecruitiFi.
