Rounded corners of graphical objects

When placing a graphical object (for example a square) in a model in ARIS Connect Designer I don't have the possibility to round the corners of that object. In ARIS Designer/Architect I do have this option, so the appearance of the the graphical objects in older models are different than the graphical objects in the newer models that are made in Connect Designer. It would be nice to have the option of rounding the corners of a graphical object in Connect Designer as well.
