Planned events in OPInt

When dealing with an Order to Cash process we create planned events for when a delivery is created and shipped. This plan is created at the time the sales order schedule line is confirmed.

So we need a process that looks like this:

ORder create -> Confirmed -> Del create -> Del shipped

The 2 delivery events dates are only established when the confirmed event is received and it should contain the dates for the following 2 delivery events. Is this possible with OPInt? If so how?
