Accessing challenge menu with no connection

As I’m one of those people who suffer from frequent DCs I’ve recently noticed that the game tends to hangup for a couple of minutes when accessing the challenge menu with no Internet connection. It just goes black for some time after which it shows challenge menu with, obviously, no challenges. Would it be possible to make it show some dialogue like “Cannot connect to the server, try again?” instead, as usually I just need to reconnect manually through my router login page so this wait is just unnecessary.
