you could write a little script like this
if all the files are from the same domain+url, you could use
rclone copy --files-from=lists.txt --http-url=https://downloads.rclone.org/ :http: remote:
the lists.txt would be just filenames, not full paths
if all the files are not from the same domain+url, you could use
for /f %%u in (lists.txt) do rclone copyurl %%u remote: -a
the lists.txt would be the full path+filename for each file
