Extended segments

Hi I assume the most recent cell libraries and most recent scr still use extended arcs in layout. Is there anyway to produce real .cif or .gds having extended arcs using s2r for a .ap file having extesions, or is this expected to be a feature of the users final layout editor. It would seem to need to be done at tech file /s2r level in order to distinguish segments from trans in view of the differing sizes of trans that occur. Also the segment table can't be used to do it? becuase other segment widths/ lengths are then also undesirably increased. The TREAT and DENOTCH dont appear to provide end extensions even when 2 same layer segments are at 90 degrees. I assume it is electrically considered desirable to use extensions? Thanks Best Regards Chris
