Requesting Official Employee Assistance: Adding Second XG1v4 4K DVR Box

Hello, 

I'm looking for assistance from an official Xfinity employee to add a second XG1v4 4K physical DVR box to my account for my family room. I specifically require this model for its local hard-drive buffering capabilities. I've already tried calling phone support twice, but due to automated warehouse substitutions, I was mistakenly shipped wireless Xi6-A companion boxes both times. I'm looking for a corporate agent who can manually secure and lock in an XG1v4 order for me without the automated system swapping it out. I understand and accept that a second physical DVR will incur an additional monthly digital outlet fee. 

Thank you for any assistance on this request!
