Saving To Clipboard with datatypes

Using DTST_CLIPBOARD it's possible to load a datatype object from any unit of the clipboard.

I've got that working nicely.

Using DTM_CLIPBOARD it's possible to save to the clipboard

I've got that working too, except I can't see how to choose th clipboard unit?

Anyone one got an idea?

Loading from any unit is of reduced usefullness if I can't save to any unit. I could write my oen code to save to clipboard, but DataTypes make is so easy it seems a waste of effort to do so.

oops I meant DTM_COPY ofcourse, no got any ideas?
