You must extend the frame structure and add an additonal field for payload.
Grep the source and you will find frame extensions where people add additional
QOS flags or piggybacking other information as well.

Not that big issue!

Why should provide NS2 this? Nobody (except you) need this feature. In the
normal case the payload isn't interessing.
