I want to change the current views (when you go to, for example, "Site Content > Pages") on Pages, Documents, Images libraries with a new set of columns so that all 100+ subsites in my site collection will all have a uniform set of columns when you go to view the Pages library (or Documents library, or Images library).
How should I go about doing this? For example when I go to mysite.sharepoint/Pages/Forms/AllItems.aspx
I want all of these particular views to have the same set of columns.
Currently, all 100+ subsites have a varying assortment of columns.
