In insight there is a transformation called "copy" where you can classify multiply items into one group.
This is great but for sitecatalyst i use saint to classify multiply items the only problem is that I have to classify every row in the saint file where as with insight you can set-up a clause that classifies multiply items all at once.
I would like the idea of adding a function to saint where you can classify multiply items by some sort of syntax clause instead of classify row by row in excel.
Multiply banner campaign tags classified by a clause of .*Banner_.* as Banner Campaign. So this would classify any camping tag with banner_ as Banner Camapign.
