Manage Smart Object Templates for different projects

Manage Smart Object Templates for different projects

Hi,
I have the same smart object that I use in three projects. The projects are subordinate to an integration project. I use a global project for central management. I can create a smart object template in this global project, but I can't instantiate it in the other projects. Is there another way to centrally manage a smart object for multiple projects?
Thanks for answer, regards, Florian
