Is there a way to take over as an existing manager?

After seeing todays news about Arne Slot (who might become the new Liverpool manager) I was very keen on taking over Liverpool with him and using this as my new save. But now I am trying to figure out how I can use him as ‘’my'' manager. I've been trying to sort it out with the ingame editor but just can't find a way. I would love to hear the solution to this!

Add Manager

I can only find a way to add a non existing manager, I want to use him with history etc.

IGE?

Yes 🙂 (I've bought it for the first time this year so I have no clue how it works)

click on arne slot and move to new club (although that may not be the scousers)

But then I cannot use him as my manager. I want my manager to be removed and use Arne Slot as my own if that makes sense?
