Risk aggregation at entity level

Hi Team,

Is it possible to have aggregation of an entity’s risks based on entity class hierarchy?

Lets say we have entity class hierarchy as:

Company

Business Unit

Application

 Is it possible to understand a Company risk profile based on its downstream entity risk ratings (i.e., the risk ratings for  Business Unit  & Applications)?

i see the risk rollup at entity level is only for the risk belonging to the class. Is there a possibility the Company ("Acme") risk profile should be an aggregation of all Business Unit risk ratings?
