Open all the disclosure triangles in a keyword collection?

Example: I have keyword collections for 9 different interviewees. In the key-collection, "Anne", there are 20 clips. Each of those "Anne" clips has marks with unique names which indicate various soundbites or topics. There are also sections marked as favorites and given names. I would like to be able to disclose all that info at once, without having to click on each discolusure triangle one at a time. Can this be done?
