[OR] What is the Open Road Equivalent of the Horizontal Element tools?

When working with corridors in earlier versions, I sometimes found it necessary to use the Horizontal and Vertical Element tools to break alignments at a specific location and other times to change the starting element of a closed alignment.

What would be the workflow to accomplish this in Open Roads?

I have an ALG of the alignments that were manually exported to native. Can I edit the ALG alignments and re-import them back into the DGN file or will that be blocked?
