Question about diverting in untowered airspace

Hi all, I have a question.

I am about halfway through my flight, the atc center has logged off, and I really have to go. I’ve seen other people on Vatsim radar where it shows diverting [new airport]. Is there a way to show that so others know I am deviating from fpl and diverting to a new airport? I’d like it to show on the vatsim radar.

Thanks

Your flight plan has to be edited with a new desitnation to show on VATSIM radar that you are diverting.
