Waiting for multiple events?

[dwing73]

Is it possible for the framework to wait until any one of two (or more) events has been received?

I can make the work flow wait for a generic ApproveOrReject event - which carries enough data to be used for either an approval or rejection, but it would be nicer to have dedicated events for each purpose.

            builder
                .StartWith(context => ExecutionResult.Next())
                .While(data => data.IsApproved == false)
                    .Do(workflow => workflow
                        .StartWith(context => ExecutionResult.Next())
                        .WaitFor(WellKnownEventNames.ApproveOrReject, (data, context) => context.Workflow.Id, data => DateTime.Now)
                            .Output(data => data.RequestId, step => ((ApproveOrRejectModel)step.EventData).RequestId)
                            .Output(data => data.IsApproved, step => ((ApproveOrRejectModel)step.EventData).IsApproved)
                            .Output(data => data.ApprovedBy, step => ((ApproveOrRejectModel)step.EventData).ApprovedBy)
                            .Output(data => data.LastRejectedBy, step => ((ApproveOrRejectModel)step.EventData).RejectedBy)
                            .Output(data => data.RejectionReason, step => ((ApproveOrRejectModel)step.EventData).RejectionReason)
                        .Then(context => Console.WriteLine("workflow complete")) // Seems to need a final step after the `.If(...)` step or it wont complete.
                    );
                    ```
