Skew Girder Ends

How do I modify the beam template to have skewed ends as detailed by TxDOT for skewed bridges?  Currently, the beam ends interfere with the abutment backwalls. ftp.dot.state.tx.us/.../igebsts1.pdf

We do not want to put the beams on a skew but rathre clip the ends where it hits the skewed abutment backwalls.


Thanks
