is there a way to achieve this with TensorCast?

add_white_noise(u::AbstractArray{T}, Σ::AbstractMatrix{T}) where {T<:AbstractFloat} = u + combinedims(rand(MvNormal(zeros(eltype(u),size(u,1)), Σ),size(u)[2:end]))

I'm not certain I know what this is doing, but in general everything in TensorCast needs to know ndims in advance. Have not explored how hard it would be to add some kind of A[i, j..., k] feature.
