How to add 3D models WITH full materials in a shared library ?

Hello, is it possible to add a 3D model with materials to a shared library, in order to easily add it to a Stager scene ?

For now, i can export a 3D model from Substance Painter with the Stager preset.  Then i can import it from strager and the model comes fully textured.  

BUT this isn't convenient with a big library shared to a team, because they will have to find the folder of the object that they want, then chose the obj inside without any thumbnail.  And this library should be in a shared folder or copied localy....  

Please. You've got a great ecosystem for easily creating 3D with the Substance suite, i can't believe you don't have a strong library system to come with.
