Ability to add/edit/remove torrent trackers on the fly

FDM (current 3.x and 5.x) is not able to edit torrent trackers right from the beginning of a torrent download as well as after the download started.
I can only do so through manipulating some magnet links that are available but not after the download started...

Please add this option so that I can speed up torrent tracking of other peers and make torrent a better choice for downloading stuff instead of direct downloads.
