I would like to see a 'group by' feature named:

The feature would accept two column names such as 'weight' and 'value' and produce the following output:

WEIGHTED_AVG = weight1*value1 + weight2*value2 + weight3*value3...

How to repeat:
This is a feature request, see description.

WEIGHTED_AVG = (weight1*value1 + weight2*value2 + weight3*value3 + ... + weightX*valueX) / X

X = rowcount
