Storing different data types in the same voxel and tree || N-sized vector grid type

[DavidCapek]

Hello, I am trying to figure out the simplest way to store multiple data types in the same tree. The idea is to store data from different modalities and be able to update the data in the voxel independently or simultaneously. Could this be done in openVDB? I have seen that defining a custom grid type should be possible, but I need clarification. Or does anyone know if an N-sized vector grid is on its way?
