Can customers Retrieve (Aggregated) Profile Data for All Sites with a Single /profile API Request?

Summary:

To clarify, currently if you send a request to /profile and include a site header (Or dont, and the request will use default site) . This controls what site data is sent on the /profile request, for multi site environments.

Content (required):

For example, the property numberOfOrders will show the count, for each site (The number of orders this profile has for each site you request). We want to know if there is a way to get this summed in a single request, rather than sending multiple request per site (For reporting purposes). In this way, the customer can make a single request to the /profile request and use the API to get a summed value for numberOfOrders rather than having to make a request for each site, and then summarizing the totals for all sites.
