Set default Max Depth filter for prefixes

[twiclo]

I recently read over #5158 and I agree with the maintainer. The new layout for prefixes is better. However I have users who would like to set a default max depth. He commonly wants to view prefixes tiet to a site and it looks when you save your filter it saves the max depth filter. Is there a way to set a default max depth all the time? Or would he have to create a saved filter for every site?

Also, is there a way to view all prefixes for SiteA from the global search bar at the top? I think it'd be doable if all of those prefixes had a SiteA tag on them
