Visio - Way to prevent text from exceeding shape size.

We have a text parameter, for an element description, which is many lines long and varies in length from element to element.  Ideally all of the data would fit within the shapes size, however, this is not happening.  Is it possible to have a shape with a scroll bar function, so rather than having the text display beyond the shape and across the page the data could be maintained within the shapes size and the user could scroll through the response.
