ADS52J90EVM + TSW14J56EVM trigger operation

I have these 2 eval boards and have them working with the "High Speed Data Converter Pro GUI" software.  I would like to use an external trigger to capture data and write the data to a file.

The SLWU087C (revised July 2015) User's Guide describes how to use the external trigger.  But, once the external trigger happens you have to click on a GUI "Read DDR Memory" button to get the data into the software. Then you have to use the File menu to save the data to a file.

There is a continuous capture option, but it isn't at all clear if it will work with the external trigger option?

Is there a way to use the eval boards & software as a triggered data acquisition system?
