Hi VLocke,
This can be done fairly easily, the simplest way would be to simply replace the contacts grid on your Customer and Contacts List screen with a detached grid based off the Customer table. You can then setup your new Customer grid so it appears similar to the original Contacts grid. If you still want to see your Contacts on this screen, you could also just create this Customer grid below in a new section, and then have two grids on your screen. Let me know if this helps solve your issue.
