Folder structure in fabricJS

Question

Is it possible to add a folder structure to a fabric.JS canvas when you export it to JSON?

for example if you have three objects it usually displays the JSON like the following:

'{"objects":[{"type": "rect", etcetc}, {"type":"circle"}, {"type":"square"}]

I would like it to be like the following:'group1:{"objects":[{"type":"rect"},{"type":"circle"}],'group2'{"objects":[{"type":"square"}]
