Aggregate values?

I am wondering if it is possible to not only see the value of the last iteration, but have numatop aggregate the values of multiple iteration?

Do you have plans of adding such a feature? Any suggestion on how to implement it in numatop?

Numatop seems to very usefull to get an idea on how well applications work on NUMA systems, but from time to time I would like to be able to get results aggregated over al longer period.
