Agentry - using oData to send a batch of transactions in one service call

I'm sending my transactions to the backend via an oData web service.  It appears that out of the box Agentry will send one transaction per oData web service call.  For my app this will potentially require many calls to the web service each time the user transmits data to the backend, causing a long wait time.  Does Agentry support batching up the transactions (of one transaction type) and sending them all in one call to an oData service?  And it would be even better if they could be sent as JSON instead of XML if possible?

Thanks
