Hi Kendall Bennett,
The concurrency settings are the same in the OpenAccess classic and the Visual Designer, it is a different UI and API but the concurrency rules are not changed. I am glad you have found your way through this and we will definitely improve in all areas where the documentation of the new API is not as complete as the one for the Classic approach. However if you need any help regarding concurrency and are not able to find it in the section for the Visual Designer, you can always have a look into the classic approach section.
