Damage enemy by animation end

I want deal damage to enemy unit by attack animations end. I use blueprints. But I want create game with mod support: add models, animations by users and so on. But this is a problem because I can not set notify on animations timeline in editor.

Ноw I can add notify in end of attack animation model, or by another desision?

May be on C++ as function in function library if on blueprints impossible to do this one.
