New plugin: Citations (with Zotero)

Hi, I use Syncthing to work back-to-back from two different computers. Suppose I export my Zotero library from computer1 to computer1.json then syncthing’d it to computer 2, how can one “append” new citation from computer 2 to this snyc’d computer1.json?

Is it possible to update this computer1.json both from computer 1 and computer 2?

Probably I can make computer2.json and symlink this computer2.json to computer1.json?
