Filter sorted by dynamic count

For filters with many values (or even top N counts), I want to be able to sort them by the most frequent values appearing at the top of the list. I want this to be dynamic (ie if I use another filter to only look at certain years, then my original filter should change order).

The example I am working on is:

I have a list of a few hundred programs. They are in a filter that is now sorted alphabetically. 

If someone wants to know what the most popular program is, they cannot tell. 

Even if I sort using an Index to have my filter sorted by most popular for all years...once I filter to just 2016, I want the list to change to reflect the most popular programs in just 2016. 

Is this possible? Dynamically sorting filters?

Thanks!
