Here is my use case: I want to set boundary values using custom algorithms. Therefore I need to read/write the field data each time step. We can already do this...

Yes, I set `warpx_amrex_the_arena_is_managed=True` and it works well. Since you mentioned the data will be copied to CPU using this method, I was wondering if we can directly modify data...
