Reload the dashboard

I'd like to reset the dashboard - so that any filters that have been applied by the user are reset back to the default (initial view). I tried this:

DS_ALL.clearAllFilters();

But that clears all filters - even the ones established in my initial view. I'd like mimic refreshing the browser - because that provides the intended result. Is there a way to mimic the refresh button using scripts in design studio? I tried location.reload() but no luck...
