GE Z wave dimmer and 3 way switch kit

Hello, new to the z wave technology but finished installing my first handful of switches. I have a local Lowe’s that carries only the dimmer switch and also the 3 way kit (not the 3 way dimmer kit). Is it possible to use the standalone dimmer switch with the aux switch that came with the 3 way kit, and then use the main switch from the 3 way kit as a standalone? Apologize if this is a stupid question, but thought I’d ask before I spend $50+ on a 3 way dimmer kit online. Thank you.

Yes, you can do this.

The auxiliary switch from the Lowe’s 3-Way kit 45638, can be used for 3-way installations of the Lowe’s dimmer 45639.
