Multiplayer question - taking over another player temporarily

I'm playing (and hosting) an online match with a friend, managing one club each.

Recently my laptop died mid-play, and we hadn't saved for an in-game fortnight. We want to try and have the same events happen as much as possible - for instance he caused a cup upset in the 'lost' period.

The obvious thing to do is to re-load and keep re-playing that game until he wins again. However, this is time-consuming for us both.

If I, as the host, select 'take control of manager' (or whatever it says) when I load the game, and then control both clubs back through to the date we were at when the game was lost, can he then take the club back over next time we play, or am I permanently in charge of two clubs then?

Hope this made sense!
