MQ Put Message Options

I am connecting to MQSeries and trying to send a number of discrete documents as a group. An MQ requirment is that a GroupID and a sequence number must be placed on each document that will ensure that event’s placement onto and subsequent pull from the queue.

An MQ resource mentioned a set of options called the Put Message Options (PMO). The PMO is supposedly separate from the Message Descriptor but I dont see any tab on the adapter that would allow me access to such message options.

The PMO would supposedly eliminate the sequencing requirement and make my life easier. Does anyone out there have experience with sending groups of data to MQ using the MQSeries adapter?
