Storing and accessing matrices in live memory in Excel

I aim to use Matlab Builder Ex to create Excel functions. The result of the function might be a set of matrices (Monte Carlo simulation returning matrices of N rows and T columns for each simulated process). Rather than displaying all the matrices in Excel, I was hoping to be able to keep the matrix result in the live Excel memory and then display parts of the resulting matrices via another function.

Is that possible? It would avoid: 1) displaying all the matrices/results in whole (space intensive) 2) having separate functions for different sets of results (computation intensive)

Thanks
