Get aggregation method when retrieving a ResultSet property ?

Hi there.

When calling a property typed as ResultSet, I get the Data + Metadata Runtime JSON, fine.

If some rows dimensions display a "Total" (as it is called in the Initial View), based on an aggregation method of the measures (sum, average, ...), is there an easy way to know what aggregation methods was used for each measures ?

I may be blind, but I did not see any property defining this (a property like scalingFactor, which is itself, defined).

Sorry if it was already asked, I admit that I did not make much researches on this purpose .

Thanks.

Br,
