Currently, when you apply a view template to a List view that has been protected, it clears the protected settings.
It'd be beneficial to have an extension of the Bulk Action Toolbar to apply sorting, grouping, adding Custom Fields or modifying protected settings. This way, you could update several views/Lists at once without needing to navigate to each view to apply changes.
This would be ideal in use cases where users are working out of locations applied by a template previously and need to enact changes/updates for several views at once.
