Restart Career

Hi all - i did try to use the search box but there were so many mixed threads and none with the answer to my question:

Is there a way i can restart my fh4 career without having 2 re-download anything? i have poor internet-connection atm so it wld be a painful to restart but im lvl 150 and feel like i rushed it & lost topic with all these icons and stories. thx for your time
