make neutrals attack each other

in a map im working on there will be groups of wolves that hunt together and groups of bears that hunt together and so on.

so what i was wondering is there a way to make the wolves attack bears on sight even if they are both neutral hostiles?

There are four neutral factions: neutral hostile, neutral passive, neutral victim, and neutral extra.

You can change the alliance states of these neutral factions in-game using the alliance triggers.
