missing idle animations from the dialogue edit response tab?

[Prometheus]

Hi , I was looking for the idle special_Waveover animation followed by a spacial_ceremony1welcome to use during one of my dialogues , but I can't select because is not present in the list of idela animations of the speaker in the dialogue animation tab , why? Its present and visible in the animation previewer of the character... so how can I do to use this animation during my scene? and only at a specific dialogue?
