Expand LatteSigma 16 GB RAM to 32

Hi there,

Perhaps this question has been answered already, unfortunately I could not find it on the Forum.

How to expand (add) 16 GB RAM to the LatteSigma model to 32 GB RAM? 

I looked at the Accessories'  page and could not find it. Maybe is there but hidden somehow.

I read few articles where the answer was pointing to the new LatteSigma with 32 GB RAM, but I do not want to buy the new LatteSigma, I wish to expand my current one (a little more than 1 year old).

I sent an email few days ago to support asking to point me the directions, but I've got no answers yet.

I wonder if I will need to buy a new LatteSigma to actually get to 32 GB....

Thank you in advance
