undoing rectangle notation, previous shape element

[KvThiel]

Hello,

I have a problem with switching on/off to rectangle notation.
In a action diagram with a matrix layout, I want to switch all elements to rectangle notation to check if the elements have the right tag.
These tags are quiet long (sentence of 4/5 words), so with the rectangle notation the shape of the elements increases. The problem is switching off the rectangle notation, because it doesn't decrease the element size (to its previous size) and it messes up my whole layout.

Is there some way to improve this.

Kind regards,

KvThiel

You could always close the diagram without saving after switching to rectangle notation.
