Allow sorting by combined podcast playtime when alternating podcasts
I like to alternate podcasts, but it's very difficult when I have 150 episodes of a 10 minute episode podcast and others that are an hour+ long. For example, the memory palace and This American Life.
A nice feature would be to be able to alternate podcasts by time instead of episode. For example, the automatic sorting for the playlist could do the equivalent of an hour of one podcast (10 episodes) and then a single hour long episode of the hour podcast.
