Expanding on Dave Sand's idea, assign a virtual sensor to the block.
The sensor is set occupied by Logix or LogixNG when both blocks on either side are occupied, otherwise unoccupied.
This is the way I have been indicating occupied turnouts, without hardware detection, for years (before the creation of the "ghost" block).
