This feature exist for 1st level and I use it a lot, I suppose it is premium
In Virtual GPS, just above the list you have a field 'group by' and you could there select 'region' or 'county' which I suppose are incorporated in region.
It give me just I want to select , combined with another filter, which of my caches need maintenance or in which county I will go walking the next WE. You could set-up a filter for each region in my country and then group by county.
Sure that direct combination could help for visted countries without the need to set-up a specific filter
