Can we do calculations in a dashboard using the results shown by the time tracking widget?

Is it possible to do calculations using the weekly or monthly time breakdown shown by the time tracking widget? We would like to use them to calculate utilisation rates. The time tracking widget shows us the numbers we need, but I’m not sure if we can actually do anything with them at dashboard level. As the time tracking data aren’t broken down by week or month in the source boards (something we’ve asked about before), we can’t do it at board level.
