Adding New Landscape Component section with custom blueprint brush

If possible, could someone confirm if you can add component sections to a landscape object during runtime.

I’ve been looking into landscape brushes and the landmass plugin, while I have found it very useful, I was hoping to be able to add landscape mesh components as my character walks around. After looking for some sort of array or data structure that held the vertices/components that make up my landscape I came up with nothing…

Is it possible to add geometry to landscapes through landscape brushes like this? or is it required to maintain its shape and size?

My thought is to add components similar to how you would do it while editing, but automatically during runtime; however, I may also be able to accomplish my goal by relocating existing landscape tiles on runtime as well. I am also aware that I can use a procedural mesh object to perform this task, and I have tried it as well, but I was hoping to take advantage of the UI and layering for landscapes as well as the landscape grass component.

Please let me know if procedural landscape tiling like this is possible/if there is some workaround to allow my landscape to extend past its default bounds during gameplay.

Thanks,
