EDI 850 import and MPS visibility

Looking for suggestions for how to set up importing EDI transaction 850 Purchase Orders, without the Sales Orders in X3 being visible to MPS before our team can review and approve? One suggestion we have received is to adjust our MPS requirements to not include Planned Sales Orders, and have the 850 transacted into X3 as a Planned Sales Order - SOP. This may work with our current processes, but I was wondering if there was a better to set this process up.
