Well you're very naughty, but as it happens I know they can redo your TK boarding passes there. However only at main entrance desks, so you have to go out of the auto gates on the upper level, airside exit (not the security entrance from landside), and the agents there are able to reissue boarding passes. The concierge desks aren't able to do this. It is on your way to the gates from there, since even you leave the lounge from the lower level you still have to go upwards to get to the gates.
