Absolutely, there's always a way. Typically if the data is sorted from high to low, you can use offsets in Table Calcs like :
LAST() - 1 (second to last in partition)
You could also rank items, and use the Rank to find values.
Etc. If you post a packaged workbook (.twbx) and let us know what you are wanting to do, we can help set it up.
