I would like to request an official feature to reset the campaign progress please.
I played the campaigns so long ago, that I would like to start a “new game mode” with all the campaigns locked from mission 1 (just like in a rpg game, etc).
Maybe this idea is not everyone’s cup of tea, but at least having the option to somehow mark (all) campaign missions as “pending/incomplete” would be great. 
You can just play them again? What are the benefits of resetting all? I dont really seen any. It only locked things you unlocked, but you can always choice to not use the unlocked scenarios.
There are 100+ campaign missions at the moment 
. Keeping track of what you played (recently) can be hard.
At least being able to tag missions as “pending” would be great.
I see I’m not the only one who wants this in his game xD
Just delete your profile in the install folder
Is there an “official” way to delete my profile data and/or campaign progress?
I tried some methods that I saw on the internet (Steam forums), but they did not work. Nearly all forums (reddit, here, Steam) report complains about the methods suggested not working
I would advise you to open a thread here as a request or something which is what I did or a suggestion on Discord
