That’s not supported from the schematic. The point to being able to add a .plot statement there is so that you can e-mail the schematic to a coworker and have them see the traces you’re talking about.
But you can save the plot settings by pressing the floppy disk icon on the waveform viewer. That makes a separate .pfg file that is used next time you run the simulation. You press the spacebar in the waveform viewer to reload the setting to restore the axis settings after the simulations completes. During the simulation, autoranging is enabled so you can see the simulation progress.
