Flaps,
no we don't. We seperate you from the traffic we know about in our own sectors, then hopefully put you back on your own nav as you like that sort of thing

, unfortunately its becoming more common these days for another heading to be needed, but now there isn't really the time to phone up and ask the previous guy, and we know nothing of what is going on on the next radar and have no intention of knowing, so sorry, but it will always happen where it normally does. The other little cup-cake I know we do is for a controller to have you on a heading, turn you left or right, transfer you, only for the next guy to put you straight back on to the original heading

As controllers, we have to have a plan and we do whats necessary to execute it, unfortunately those around have no idea what you are going to do so again, it will happen. Sometimes it can help what the previous guy does, setting up a resolution to a conflict they can also see, but normally there's more than one fish to get fried in the sky.
