Update existing .json instead of completely overriding it

Question

I've created some diagrams that are a little complicated, so I've had to disable autolayout and move them around manually using structurizr/lite for better readability.

When I add a new element to the view and refresh the lite webpage, all other elements still have their original placements. I was wondering if something similar would be possible in the cli version; since right now, using export -format json on a .dsl file, completely overrides the previous .json and all its manual placements.

I couldn't find anything on my own. Is this functionality possible, or is it not implemented here yet?

Thanks.
