Reserving Bases during war

With scouting made redundant during prep day, is it possible for SC to implement a feature where we would be able to book a base in game? Something similar to clash caller?

We used to issue the ID on prep day and people would book bases they want to attack. Now prep day is pretty much redundant..

I think this is a good idea - tap to select as a preference kind of thing

Or leader assignment option.
