Making players available for reserves?

The new feature seems good, but has anyone worked out how to use it properly yet?

There seems to be no option for "make none of the 1st team squad availble for the reserves". I've also had 1st team players tired as they have appeared for the reserves a day before a 1st team game.

As I say, the feature sems a great way of keeping fringe 1st team players fit, but have you worked out how it works yet as I'm obviously doing something wrong.

Thanks

As long as the player is not set as Available for Reserves he shouldn't play for them.
