Feature Request: add option that use the Motrix's download folder instead of browser's download folder

[cdytoby]

I set the browser default download folder to desktop, and Motrix's download folder to somewhere else.

And I noticed that when this plugin is intercepting the download and give it to Motrix, the file will still be downloaded to desktop instead of the Motrix's one.

I hope after plugin intercept, it should not give Motrix the target download location, it should be determined by Motrix.
