Not available yet, but hopefully it will be in future releases. 

Would be great to see this functionality in Aurena - Group and Sum advanced searches on overview screens have been heavily used in IEE (and in Centura before that).

 In IEE customers could write their own SQL and use the group and sum functions. There are two sides to this in Aurena, it's not only a client issue but also requires IFS to make changes to OData layer as well. 
IFS will prioritize the flexibility needed within the product teams when developing this type of capability
