The title says it all, that would be something really helpful to allow more brigades to take control of outposts and thus make it more competitive.
I myself cannot be there for outpost because it is at 2 am local time, and having to transfer brigade leadership to get one outpost is not something I really wanna do personally at the moment.
I'm surprised that this hasn't been implemented yet, and I really hope this will be done soon.

I am looking forward to see your opinions, though i doubt there's many reasons to refuse this.
