Allow data request to be sent to vendor from code

I discussed this with Svetlana to request data from a vendor using an InstrumentDataRequest and she confirmed that this is not possible from a script - https://www.multicharts.com/discussion/viewtopic.php?f=19&t=53729&p=140019#p140019

This would be helpful to be able to refresh data programmatically rather than having to use Quote Manager especially in the case where data is missing for some reason that you are trying to backfill. It would be great if you can do the following to force a data request to the data vendor for a specific date range:

    InstrumentDataRequest request = Bars.Request;
        request.Subscribe2RT = true;
        **request.RequestFromVendor = true;    ///force data request to the vendor, when you view the Quote Manager status window you should be able to see this request there.**
    request.Range = DataRequest.CreateFromTo(missingBarRange.Item1, missingBarRange.Item2);
        request.Verify();
        DataLoader.BeginLoadData(request, OnData, null);

Thank you in advance for your consideration.
