Is there any way to trigger Event Flags in Red/Blue/Yellow(?) through PKHeX?

[notInfi]

As in, we can reset the events using PKHeX, but can we do something to trigger them through the app?

I can't seem to find any option. If there is none, I would like to request one, so that the menu has checkmarks like all other gens. I don't think it should be very hard considering the system is already in place for later gens.

I have only used this on R/B, can't say much about Yellow. Also if this isn't feasible/possible, can someone guide me to do so manually?
