Manually operating grade crossing signals

[Rscott417]

I have a grade crossing that I want to add nj international crossing signals to but the crossing is very close to the edge of the layout. I wanted to use the logic rail crossing pro but the infrared bulbs would have to be mounted on the removable extension which would then need to be able to get unplugged to remove the extension. Is it possible to wire a switch to the logic rail crossing so as the train approaches I can manually turn on the crossing signals then turn them off when the train has passed?
