import data into JigSaw v2

1
I am working on this Speculation project. I do import data into Jigsaw. The standard fields like time/date. Location, Latitude etc.

BUT, how do I import the extra fields? The [Categories]? I can create the categories in the JigSaw file. But how can I make it understand to import it from the coma delimited file? It drives me nuts.

I could just construct the JigSaw file myself, by programming it. But I just find it silly.
