SSRS Subscription ParameterValueOrFieldReference Default Value

Question

We have a .rdl file with parameters Available values coming from Query.

In the cascade drop down one of the parameter, we have set available values from query and also set default value -1 Screenshot

We are using reportinservice2010.asmx for creating subscription by passing parameters like below

List<ParameterValueOrFieldReference> parameters =
    new List<ParameterValueOrFieldReference>();
parameters.AddRange(
    rpt.ParameterNameMappings
    .Where(p => p.IsMappingFieldAlias)
    .Select(p => new ParameterFieldReference()
    { 
       ParameterName = p.ParameterName,
       FieldAlias = p.ParameterFieldAliasOrValue }));
parameters.AddRange(
    rpt.ParameterNameMappings
    .Where(p => !p.IsMappingFieldAlias)
    .Select(p => new ParameterValue()
    { 
       Name = p.ParameterName,
       Value = p.ParameterFieldAliasOrValue }));

Above parameters we are using below:

rs.CreateDataDrivenSubscription(
    report.FullName
    , settings
    , report.ReportSubscription.SubscriptionDataRetrievalPlan
    , report.ReportSubscription.Description
    , report.ReportSubscription.EventType
    , report.ReportSubscription.MatchData
    , reportParameters)

Problem : The subscription is getting created but the default values are not set in the screen of subscription edit. Other parameters which are not default are getting saved as Get Value from Dataset.

Solution : We need by default to set as "Use Default value"
