I wizard does not support combining jobs. You can load a job file,but that will replace the previous job. You can, of course, make a job contain as many operations as you need, so 3 arcs in one program is easy.
If you want a job to end with a move to a specific location you can use the user Gcode operation to add whatever move you want.
I dont understand you arc problem and could not find a posting anywhere. You can post photos right here to this topic.
