Description
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]))

Research direction
Start by reading TensorCast's @cast syntax and examples, then compare them with the add_white_noise function shown in the issue. Determine whether @cast can express the operation across the remaining n-1 dimensions of the tensor, and treat support for that expression as done.
