Tradestation & CSI data

Hi. I was wondering if anyone out there has had experience importing 3rd party data into Tradestation, specifically CSI data. Tradestation's website says it supports CSI data, but so far the only way I can find to import is to go through the painstaking effort of selecting 3rd party data source, one by one, when plotting a chart. Surely there must be a way to do a bulk import of 3rd party data.... I am trying to incorporate 40 years of historical futures data from CSI.

Any tips/comments?

Thanks
