Feature How to set up callout boxes to automatically resize depending on quantity of text?

[jamboverde]

I am currently going through a long document and I am making comments as I go along, using call-out boxes. However, some comments take more than one line inside the box and it is not auto-adjusting its size to show all the text that has been typed. I am currently only getting the first line showing and, if I want all the text appearing, I need to manually stretch the box every time. Is there a way I can set the call-out boxes to auto-adjust, depending on the quantity of text?
