[ADMB Users] What is the 3D version of save_dvar_matrix_position() and relatives?

I'm working with a model, which requires a spatial grid. In each grid point
I need to evaluate the likelihood of a vector of observations by comparing
with predicted vector for that grid point. I do that using a multivariate
normal distribution. Since both the predicted observation vector and the
covariance matrix of the MV normal distribution depend on model parameters
I need adjoint code to avoid excessive memory use. However, I wasn't able
to use 3D alternatives to save_dvar_matrix_position() (and similar calls)
that work for matrices. I tried save_dvar3_array_position() with the result
pasted below. Am I overlooking the correct class/command to use? if not,
can anyone suggest a possible solution to this (keeping my limited cpp
skills in mind).
