Get bulk updates for Books/Raw books web sockets

[hardor]

Hi,
Bitfinex says
Bulk Updates
Bulk updates can be enabled by sending a conf event with a flag value of 536870912. With bulk updates enabled, updates will arrive as an array of arrays.

Now SubscribeToPartialOrderBookUpdatesAsync method returns only one item for asks or bids each time. And we have a lot of responses.
Can you add new parameter if we want recieve bulk updates?
I guess it is enough add one line for it
messageEvent.Connection.Send(new BitfinexSocketConfig { Event = "conf", Flags = 536870912 });
