Leaking filament with dual extruding

Hi there,
I have a Leapfrog Creatr Dual extruder and uses the newest version of Simplify3D.
There is a (well-known) problem with leaking (oozing) nozzles when I print with two colours.
The nozzle which is in standby modus, leaks some filament on top of the other printed part, due to the remaining hot temperature of the nozzle
I was wondering if somebody knows any settings that could keep each of the colors separate for a better look.
I want to print a 2 mm thick business card with ABS on the sides and top and white PLA on the down site.
I have already set the following settings: Ooze control: Retraction distance: 3 mm and ‘wipe distance’: 5 mm.
I think a good solutions can be: adding some specific gcode on the tab ‘Script/‘starting gcode and ‘/toolchange-gcode’ in the menu ‘FFF settings’. Something that retracts the filament of the ‘in-active’ extruder.
In the ‘starting code’. Is already set the following standard code. I think here and in ‘toolchange-code’ we have to make some changes.
