Connecting two Pixhawk-equipped to 2 different aircraft to a single Mission Planner instance

I am working on creating a two-plane swarm using Pixhawk 2.4.8 and need help connecting both Pixhawks to a single ground station (Mission Planner). My goal is to designate one aircraft as the leader and the other as the follower. Is this possible? If so, how can I achieve it? I am new to this and would appreciate any guidance.
