Can the world partition grid be accessed via blueprints? c++?

I have several gameplay systems that rely on world position. Typically I would get a vector and set a radius around that point to determine where something happens, but with world partition and the grid cells it would be a incredibly handy to be able access the grid, especially through blueprints. Is this possible?

For example if I want something to spawn within a certain area I can define which cells it’s allowed to spawn.
