Two Pro Power Kit

When I originally installed my Ring Pro, I had to install the Pro Power adapter on my door bell in the house, and then the app told me I needed to swap out the power converter in my garage that powers the door bell. That all went great until I realized that my house had two door bells mounted on opposite ends of house. I noticed this because the second one I was not aware of was humming like crazy one day. To resolve this, can I just buy an additional Pro Power Kit and install on the second door bell?
