Is it possible to add/sum values of various columns in RadarScreen?

I've seen an example on how to add values from various rows using "GlobalDictionary" and "GetAppInfo ( aiRow )".

Is there a way to reference different columns? That way I can sum the values into a new column/row?

Simple solution - but potentially messy - combine the indicators you are using in Radar Screen into a single indicator. Not sure if that would work for you. Short of that things get more complex.
