Enable Object Oriented List Management in Excel

#### Description:
At present, working in Excel does not allow list structuring (a la Grasshopper) when you apply an engine method to a list of objects nested within a cell it does not return a value (much less a list of values, summed.) The issue below details this for dealing with a list of pipes - we have no desire to expand that list out into its thousand pipes, we would like the sum of the query for solid volume to be enabled in a single cell.
