title: Payflow Pro .Net SDK (Payflow_dotNET.dll) missing CUSTREF option for Inquiry Transaction command
body: <p>I suspect its just missing from the Payflow_dotNET.dll library (I checked version 4.50) but wanted to see if anyone else noticed that you can't use the inquiry transaction command with CUSTREF. Their <a href="https://www.paypalobjects.com/webstatic/en_US/developer/docs/pdf/pp_payflowpro_guide.pdf" rel="nofollow" title="SDK documentation">SDK documentation</a> references it on page 39.</p>
  
  <p>I don't believe you can just use CUSTREF in place of the ORIGID parameter but maybe someone else has more experience with this than me.</p>
