RSS feed with query parameters

Thank you so much for creating this plugin! Even if I can’t use as I originally planned, I know there’s many more uses I’ll be able to find for it.

1. I want to use a product feed that I usually specify a query string of parameters after the RSS URL, such as my affiliate ID, category id, product keywords, image size, etc. Is there any way to accomplish this, especially getting my affiliate ID to be inserted in the link?

2. I would like to display one product daily (or maybe 2x a week, etc.). These aren’t new products created daily. Is there any way to rotate through items in the feed?
