Question on adding a brand name owned listing when reseller listing already exists

Hi,

I own and have registered with Amazon brand name.

I have a website where I sell my person IP products. I have resellers who resell our products on Amazon.

I would like to list my own products the resellers have listed, but use my own listing and item names/SEO. How do I enter this into my Manager Inventory and not affect or collide with the items my resellers already have listed. I own the GITN. My GITN will match the GITN the resellers listed with. There in lies the problem when I try to add my product to the inventory. How do I handle this situation in Amazon Seller Central? Thank You
