Segmented Regression in RapidMiner?

http://en.wikipedia.org/wiki/Segmented_regression

Any suggestions on how to do segmented regression in RapidMiner?  I'm willing to specify the segment breaks manually, and I understand that I could construct a network to subset the data at the breakpoints and tree off into separate regression models for each subset, but is there a better way to do this that doesn't occur to me?  Or an operator that can do segmentation?

Thanks for any help!
