So there is absolutely nothing in the PSE user guide about how analysis templates are handled in derived templates. And while it appears that it is possible to override an analysis in the base template by creating one with the same name, there is little to no content about it - PI Square, Live Library. The User Guide should discuss how analytics are handled in derived templates. I guess you could punt the discussion of overriding analytic templates to a link to content on the portal - IF you would create that content (not just a PI Square post)- and maybe if you make the portal actually perform...
Given the still questionable performance of the new portal, I depend on the documentation that I can download because I know it will open every time I make an attempt.
