Request: Paste/Fetch - allow 1 upload job per URL instead of 1 job for all URLs

Hello,

I was importing some files from SRA with Paste/Fetch, by pasting the URLs into the text box, and noticed that if I pasted all links (12 files) into the URL box (see screenshot below) it seems to run as 1 big job that took > 40 mins:

And if I pasted one URL per text box like below I could get the files to upload as separate jobs that then took less than 10 mins to the load the 12 files.

I like the faster method but it's a little bit of a pain to have to copy each link into a separate text box in the Paste/Fetch so wondering if there could be an option for pasting all URLs into 1 text box (like in the first screenshot) and then having 1 upload job per URL instead of 1 job for all?

(with the 1 upload job per URL, as in the second screenshot above, I think it's also nice to see the datasets turning green quickly in the history as each file uploads, rather than having all datasets spinning yellow in the history for > 40 mins & not knowing if the upload is working or not, which is what happens with the method in the first screenshot)

Some info:

First screenshot leads to upload of all URLs together:

Start with tools/data_source/upload.py and trace how the Paste/Fetch form submits multiple URLs and creates upload jobs. Verify the behavior with a multi-URL submission: each URL should become a separate job, and datasets should update independently in history.
