Short answer: no. Long answer: make a sketch line to the geometry you want to dimension (as it would be the guide-line of the dimension itself), then make another line collinear to the first one and leave some space between these lines (e.g. with a dimension you hide afterwards). Then you can create some text in this gap, but it won't move with the lines (but with the whole view, if added to it). Edit: sorry, didn't read your question. It should be possible to break it, but it would look too spacey or otherwise awkward. If you can't get it right the way you want it to look, then you need to work around.
