Can you edit active swarms in Pokémon Gold/Silver/Crystal?

[Woodierbean]

I would like to edit my save to have a Dunsparce Swarm in Gen 2, but I don't know how to do that in PKHex, or if it's even possible. Can anyone help me?

That's the location on wram, I checked and it is saved in the sram (savegame). So yes, the swarm can be edited on savegame/cheatcode.

It seems this is noy in pkhex, I can search the swarm locations and try to make a plugin to edit them.

If you sre on emulator you could also use a cheatcode, not sure if there's any.

Edit: it seems in gold/silver it is a little more complicated as it isn't handles by a single flag and there's grass and fiahing swarms
