Document Packet

Hello,

Is there a way/setup that can be made in TN, so that all the outbound documents do not go individually, but they are packetted into an envelope and sent at a predefined schedule or when the size crosses a threshold which ever is earlier.

For ex: when we are sending the acks, it is better to send all the acks packetted together

Should a custom logic be built or is there a built in functionality for this.

Thanks
Bhavani Shankar
