Hello Cliff,
Not currently, you are the only person who has asked for such options. Can I ask why?
As for iTunes, the iTunes author field is part of search, you should not have to put the author in the title, if search is the reason.
As for the date, wouldn't you want to enter this per episode to look exactly how you want it formatted? There are many ways to format the date which would make such an option complicated. The data meta data is also arleady part of your listings, it is used to determine your latest episode. Search wise, there may not be value in including a date and depending on the format, could conflict with your episode titles.
Your reasoning for this will help me determine if this is an SEO feature or just customization for a specific use case.
Thanks!
