Automatical change of the heigths of slim lanes

[phadreus]

Hallo, we use swim lanes in visio 2013 to organize our BPMN workflows. If we add a new shape (via shape > mouse over > blue arrow), the height of the slim lane is changed automatically. Although the original slim lane provides sufficient space for the new shape. Is there any possibility to switch that automatic resizing off?

Thanks Phadreus
