Text animation per block of text

I have a slide with 3 text frames. I want to animate in such a way that at one click one text frame appears as one complete frame (without borders, only text). There are 3 options: animate at paragraph 1 level, animate as one object, animate paragraphs together. At “level 1” the lines appear one by one per click, I do not want that. At “one object” and at “animate paragraphs together” all 3 text frames appear at the same time at one click. I do not want that. I suppose that the implementation is wrong, so that it will be a bug. But I am not sure. Can any body help me, please?
