Deleting Trophy, Club & Player History

Hi there, apologies if this has been asked already but i cannot seem to find it anywhere.

Basically i want to start a new game from scratch but i have some gripes that annoy the hell out of me.

FM18 and FM19 just don't come close to FM17 so i like to do the data updates by downloading the transfer updates and such like. However, the league history annoys me because unless you reduce the year by 1 each time then you cannot update the league history correctly and it looks odd.

Example would be:-

2016 English Premiership Winners would be Leicester City

You can change the current champions by editing their last position but in order to update the history you'd have to reduce the year by however many seasons out of date the game is. So if you wanted it up to date for the current season and have Man City as the last champions then the history would look like this:-

2016 Man City
2015 Chelsea
2014 Leicester City

Otherwise it looks weird and is listed like this:-

2016 Man City
2016 Chelsea
2016 Leicester City
2015 Chelsea

So what i like to do is completely clear the history so there are no previous winners, or at least only 1 previous winner (just to ensure the European competitions are made up correctly).

So what i am looking for (if it is possible) is a quick way of deleting all the history, like of everything, even international competitions without having to tediously go through league by league, club by club and clearing it from the editor to start a fresh.

Does anyone know if this is possible?
