Can it be done, if so what is the syntax?

The method takes the URL pointing to the entity, not key properties. Now most of OData servers use a convention to address entities by using key properties in the URL. That convention is described here http://www.odata.org/developers/protocols/uri-conventions#AddressingEntries. But I would strongly suggest against trying to compose that URL yourself (it’s easy to get it wrong).
Maybe if you posted what is the scenario you want to get working, a better answer could be possible.
