Assuming that I use an EDU with almost all missile units switched to "skirmish" class (AI handles them better), is it possible to make a skirmishing setting distinguish between javelin and other missile infantry units (archers)?

Additional info: my question excludes gunpowder and crossbow attributes, e.g. XAI uses <skirmish-infantry> and <crossbow-infantry> settings, I'd need something additional like <"bloody archers set to skirmish"-skirmish-infantry>. I know it can be done via giving archers crossbow attribute, but that's a bit questionable. Any other ideas (tried giving units some dummy attribute, ofc it didn't work )?
