It is. I used the Create Data Plugin Function so I could load files without using the wizard every time. I didn't manually edit anything in the script.
Programming Data Acquisition and Control in Measurement Studio and Labwindows/CVI
DIAdem 2011 should load your 60 column ASCII file several times faster than DIAdem 2010 or earlier versions. If you do not see significant speed increases-- perhaps as much as 5x, then we should take a closer look at that DataPlugin. The ASCII file format you describe should load MUCH faster in DIAdem 2011.
This was implemented for DIAdem 2015.
In the DIAdem settings for NAVIGATOR -> Loading behavior you find the configuration for it.
