Thank you for your forum post.
You can create multiple settings files by saving a waveform as a 'settings file' oppose to a 'psdata file' but you cant load them in such a way that you can choose between them within the software. What you can do though is once you have a file configured to your specification i.e. Probes are set, ranges, filtering etc, You can then simply either save it as a settings file or a normal waveform and then re-open these into the PicoScope Software as you normally would.
What ever changes you make within the file, once you save it, the settings will be saved therefore you can just simply re-open it to the desired settings. This would then allow you to have settings for Ignition, Sensors, Actuators, and other settings you feel more comfortable with.
The key difference to remember though is with a psdata file (Waveform), when you reload the file it loads all the settings and the data i.e. waveform, that were saved, then you need to press 'Go' to start sampling.
With a settings file however, there is no data displayed i.e. waveform as this information is not saved and once opened the software begins sampling straight away with the settings that were saved into that file.
I hope this helps to answer your question.
