Would like to have a checkbox when creating corridors and named boundaries (particular to cross sections) to allow users to choose another geometry to pick start and stop stations.

Example, I built an alignment alongside two other adjacent alignments, just for the purpose of applying a corridor and template. But the start and stop stations are based on the adjacent alignments. Would like to be able to check the box and then identify the adjacent alignments to pick the starting and ending stations to create a corridor and when creating the named boundaries. (shown in attached PDF)

I know I can graphically create the geometry at the correct start and stop stations but would like to be able to create cross section named boundaries at correct adjacent stations. And adding the ability to corridor creation would eliminate the graphic process of creating the alignment to adjacent stations by just selecting the adjacent alignments and stations.
