DescriptiveStatistics for Vectors - how to get stats for the norm?

Hi,
I’m trying to get some statistics about a vector field using DescriptiveStatistics filter.
It seems that I get the stats per component of the vector.
I would like to have also stats on the norm of the vector field.
Do I need to create extra scalar field for the vector norm for this purpose or is there a more straightforward way?
