Pipeline: force stocks inclusion regardless of screening

Sometimes I need to have some particular stocks in the pipeline for reference or comparison (e.g. SPY if I am interested in the market overall ) but it could be that the screening process remove those stocks away. So it would be great to have a function to force a sid to be present in pipeline results, regardless of what screens are.
