Yes, there is a"software" solution ... rather two solutions now.
Steve_G added a "ghost" block to be connected to a turnout.
When both real detectors on either side of the turnout are active, the "ghost" is active.
?
I haven't used the "ghost" as my layout predates that feature.
I summarize my "software" approach in my blog ?...
