How to move comment text balloons? They are in my case located too low

Commentary, when exported ‘flattened’ gives a nice view of comments in text balloons, flexibly connected to the original text to be commented. Why cannot I move the commentary balloon to the top of the page f.i., thus avoiding commentary-texts appearing on the wrong page?

Thanks in advance.
