In APD and SiP, you do not pre-define bonding points on the pads. Rather, you spread the wires per your manufacturing rules using the Route -> Wire Bond -> Tack Point Move command. You can choose to manually move wires a specified distance, move wire ends interactively, or have the tool automatically spread them evenly either parallel or perpendicular to the die edge.
There is, I believe, even a DRC check for wire end to wire end clearance. It's in Constraint Manager, under the Assembly workbook, Wire folder, Wire-to-Wire Online Spacing page. The column name is "Wire End to Wire End".
