Thanks for your feature request. I’d personally love to have this as well (but not a developer so I can’t contribute code, unfortunately). In fact, we’re not alone with our desires: quite a few people also indicated their interest in this feature over at GitHub, where AntennaPod is being developed.
I have good hopes that this will be implemented at some point. But it ties in with a loooooong other discussion about ‘newsy’ versus ‘serial’ podcasts, so I think it’ll need some thorough thinking on both requests and how they can be simple, effective and flexible at the same time. In other words: it will probably take a while.
