2 Remotes on 1 C71KW-400

I have a HDMI splitter going to 2 TVs on the same C71KW-400 receiver. I have 2 VRC82 remotes, 1 for each TV. They both show up as R2 in the settings. If I change the TV brand on 1 remote, it changes for both. How can I program 1 for each of the TVs? I know both TVs will show the same channel, but I want to be able to control the volume and power independently.
