How to use these two properties related to segmental bridge?

For precast segmental bridges the user defines lengths of real bridge segments so the distances between the segment points (stationing) will be calculated, that these lengths are achieved. The lengths are considered between specified points, that are defined by a geometry point in the cross section. The stationing will be calculated from one segment point the next/previous one based on the input length. The cross section at the point may be rotated and stretched. The segmentation will be executed with a calculation inclusive evaluation of formulas. 

To modify the direction of the segmentation you can choose in direction of stations or against them.

Is there a similar way to control segment geometry in OpenBridge Modeler (the above being for RM Bridge)? i.e. on an OBM segmental bridge is there a way to define the first casting segment with 90 deg stop ends both sides and then have the subsequent segment geometries follow on from this with a 90deg stop end on one side and the other end match cast with the previous segment? Or are the segment ends in OBM always set perpendicular to the alignment?
