Grant,
Search the help file in Trace with regards to GSHPCalc. There is a .csv file that Trace generates ("file name".GL4.csv) located in the same directory as the .TRC that has the information you are looking for. This .csv file can be imported by GSHPCalc. Use with caution - make sure your load file is accurate; otherwise your GSHPCalc sizing will be incorrect.
Hope this answers your question.
