How to get distinct values applying an azure table storage query?

Question

I want to get the "ReceiverEmail" values of a certain PartitionKey "emailAddress". I want to retrieve only the distinct values of the ReceiverEmail. I am applying this python query on an azure storage table as follows:

entit = table_service.query_entities('UserRequests','PartitionKey eq \'' + emailAddress + '\'',select= 'ReceiverEmail')

Any help of how to get distinct values ?

It seems that it is impossible to directly query distinct values. This official document states the operations that are not supported:
