Of course that's something you can do. Here's some advice on how to do it:
On the Customer List screen, you may want to consider moving the Job of Customer field to the Address Info section (it's currently in the Additional Info section) and then set up actions that retrieve the address info from the Customer table for the parent customer. You can either add a button that when clicked pulls the parent address info, or I would prefer to trigger the action on text change of the Job of Customer field.
Good luck with the customization and remember to back up your original screen first so you can always revert back to your original! Or feel free to take advantage of our promotion and have us do the customization for you - 30% off all customization packages.
