Calculating Volume By Filtered Items

Lists-Logic
1

Hi,

I’m trying to group elements that have the same material name and then calculate the total volume of each group and then export to excel.

I’ve managed to create a list that has each elements name and volume in a branch but i’m unsure how to actually go about grouping them together. I suspect this might be quite easy but pretty new to dynamo (come from a grasshopper background) so any advice / suggestions appreciated.
