It was *then* that I realized that the UI for this feature has not yet been ported to Java. It's still in C++ only.
Of course, I haven't ported my code to the C++ side yet. And one library that I was using that made it simple to write a particular routine I need doesn't have any C++ equivalent. I can write the necessary code to do what I need done, but it will take a little time to get it right.
So we'll see how this works next week.
