Currently it difficult for customers to know what can be saved as part of their reporting template to the gallery as things are somewhat disconnected and it is not clear what will be saved as their template.

It would be great if customers had a central place to create their template (almost like the page master) but better :-). I place where they should be able to create standardized table templates, create their visualization templates, global font colours and sizes, global font families etc. A place where they can setup their standardised sig testing. See example below
