Hello,
As per Cameo online help
"Displaying Pins
To display Pins on shapes
On the diagram pane, select any number of shapes on which you want to display Pins.
Open the Select Pins dialog by performing one of the following steps:
- From the shortcut menu, select Display > Display Pins.
- On the diagram toolbar, click Display and select Display Pins.
In the dialog, select the Pins you want to display.
In the Layout options area, specify the Pins' layout on the shape:
- Top/Bottom - displays Pins on the shape from its top to bottom.
- Left/Right - displays Pins on the shape from its left to right. "
However no matter which option is selected the pins are always displayed at the bottom of the call behaviour action shape.
Best regards
