DWM3001C initiator and responder

I have 4 Dwm3001CDK boards and I am going to implement simple indoor localization setup. My idea is to place 3 anchors (dwm3001cdk boards) in 3 different places and attach one DWM board to the moving object. My question is should I make 3 anchors as initiators in Fira ranging session and moving object as the responder or vice versa ? What I realized that one single initiator can start multiple TWR (Two way ranging ) with several responders (multicast mode) but one responder can respond back to its own unique initiator. Am I right ? I would really appreciate your suggestions for my implementation.

Thanks and Best Regards
