It would be helpful to have a library of components, and styles to be shared with your team regardless of the project. It would act similar to the template, but more flexible and dynamic.
This would allow for faster builds and more accuracy across projects without using a third-party DSM.
This is a similar idea:

Yes, but it's not a true shared library. For instance, there is no version control. So, if changes are made to a component on one project, the same component on other projects is not updated.
You can create a private password protected page for each project and use it as a library for assets. Or even dedicate an entire project just for a collection of components. Copy+paste works across projects.
