Add Region BEFORE Existing Corridor Region

I am currently working on a script that I almost have done, but one final part is throwing me off. I need to adjust two regions in my corridor and fit in a new region in-between them. When I add a new region to the corridor through Dynamo it adds the region to the end rather than in between the two existing regions. This then gives me a stationing error based on my begin and end station of the new region. Has anyone found a way around this?

Hi @jbrunkhorst,

Which version of Civil 3D are you using? We fixed this in Civil 3D 2026.1.
