Table Saw Extensions

[Warncorp]

I have owned a TS24120 for about 3yrs and would like to add a right extention table. Are longer rails available from Ridgid that would provide for 50" to the right of the blade? If not, does anyone have experience with adding a right extention table to Ridgid table saws while maintaining the original rail and fence set up? I would prefer to modify the existing Ridigid fence and rail system rather than replacing it with something like a Beisemeyer.
Any information that you can provide related to right extention tables for the Ridgid table saw is appreciated.
