Pairing Vizia RF+ 3-way Dimmers

This weekend, I installed two Leviton RF+ dimming switches that are supposed to support “Z-Wave beaming.” The VRMX1-1L replaced a single-pole switch on top of the basement staircase. In the basement at the bottom of the staircase, I installed a VRCZ1-1LZ 3-way RF controller. The Z-Wave RF control protocol is supposed to make up for the lack of a red traveler wire between the switches and allow 3-way functionality.

Unfortunately, the instructions do not show how to pair the two switches. Instead, the instructions only mention how to add the switches to a central Vizia RF+ controller. Rather than purchase the Vizia handheld controller, I prefer to purchase a Z-Wave hub. Has anyone successfully paired Vizia RF+ 3-way switches using a hub?

Thanks in advance for your advice.
