Which assets cannot be shared in the solutions gallery?

Correct Answer is: Custom Dimensions

Explanation:

Google Analytics has created an excellent (and free)  gallery of advanced tools, pooling the efforts of the community of web analysts around the world. In addition to the Google Analytics team itself, the world's most disproved authors such as Justin Cutroni or Avinash Kaushik himself contribute to the Google Analytics solutions gallery. Anyone who wants to contribute something useful and help other analysts can also contribute.

Through this gallery, by importing certain elements, it is possible to fully customize a Google Analytics view, without having to be an expert in creating these types of advanced settings. It is available only for users logged into Google.

To incorporate a given solution in our profile, simply "Import" and select the view to which we want to add it.

The solutions offered are of four types: dashboard, custom report, segments, and attribution model. Some can be imported to only one view at a time (dashboards, custom reports), and others to all views at once (advanced segments).
