[Feature] Setting to upload a single file at a time rather than a batch at once?

Is your feature request related to a problem? Please describe.
Attempting to upload Gamecube iso's. Rather than uploading one at a time it's uploading 50 different games at ~50kbs.

Describe the solution you'd like
Only upload one game at a time and pause the next upload until the first one is done, this way it would be possible to resume easier.

Describe alternatives you've considered
Uploading them by hand one at a time, but someone has to sit at the computer and only send a few on each time. Somewhat unrealistic.

Great program though, and this is a small nitpick! Thanks!
