Caan't Pause Downloads

I noticed that is is not possible to pause a download and resume it later. I can only only stop a download after which I will have to restart the download again from the beginning.
Is it possible for an option to pause download to be added

If you exit the app, the download will continue to run in the background for a minute or two, and will then automatically pause.

Re-opening the app would then allow you to resume the download.
