One convoluted way of getting the effect you described is to use a working .cfg file to autolocate TiPS, then set the Lighting Constraints/Sun at Ground Site to 'Day only' or 'Sunset to Midnight' before plotting ! Since it is so easy to Load and Save configurations in SkyMap, I have working template files for common tasks, like current favourite objects, identifying a bright unknown, ditto faint, all bright objects from a large tle file, predicting for friends, etc... I also save copies under different names during a night, so I can easily rerun an earlier chart, in case something interesting is discovered.
