Azure Graph API. Assigned licenses of customer subscription

Hi guys,

There is a possibility to get assigned licenses for customer tenant using Azure Graph API making request to https://graph.windows.net/[TENANT_NAME]/subscribedSkus?api-version=2013-04-05.

It returns data grouped by SKUs. If customer have several subscriptions with the same SKU (e.g. 2 "Office 365 Enterprise E1" subscriptions) than I get total number of assigned and prepaid licenses per SKU. Response contains no data about subscriptions customer have.

Is there any possibility to get number of assigned licenses per each user subscription?
We would like to show this information to customers. 

Thanks a lot in advance!
