Allow us to title group chats OR Allow a crew to have subchat categories

For battles & wars specifically, and for other group discussions generally, crew chat is often not the best place to hold a chat, but if you're in multiple group chats with some of the same people, it can quickly get confusing which chat is which. Being able to title the chat (or even better, the ability to create subCrew chat rooms that use the main chat format) would solve this quickly and shouldn't be hard to implement (sub crew chats would be significantly harder, but also very much appreciated by everyone who uses a cellphone to game, because the PMs can fill the screen during a game instead of just appearing at the side of the screen).
