Use FeedMe with a dynamic URL
There's currently no way to achieve this with Feed Me. A single feed would represent a collection of items to be imported as elements/entries.

One method your could consider is setting up a feed for a single entry, then use the optional url parameter when calling it via the direct feed URL. This overrides the URL used in your feed settings with the one you provide.
