Rendering purge line in Prepare mode

I’ve noticed that when I open a 3MF file that’s configured to use an X1 printer, I see a purge line on the plate when I’m in Prepare mode. It seems to be mixed in with other lines printed for X1 automatic calibration. Is there a way I can render the purge line like that when using a P1 printer profile?

I know I will see the purge line in Preview mode after slicing.

I want to see it in Prepare mode so I can avoid arranging objects on top of the line. If I have a complex model and/or a very full plate, slicing takes a long time and I have to keep switching back and forth between Prepare and Preview to see if I’m over the line. It would be much easier to just see that rendered on the plate like the exclusion area while arranging objects.
