How to set mutilple urls as source

Problem/Motivation

So , here the scenario,

I have configured a csv feed with url as source. The feed import works well, for running a single url import. However, what I am trying to achieve is that I provide a list of urls as source, and then each url is parsed and saved after processing.

Can anybody guide in the right direction about how can I set list of urls as source, and then I can be able to run the importer which fetches the data from source urls one by one. Is there any hook or event that I can make us of?

Any help will be greatly appreciated, Thanks!
