SPI with MAX3865 and multiple temperature sensors

Hello ! I am trying to do a project about PT1000 sensors and a MAX31865 board with SPI communication.

It is working perfectly, you can see in the images attached, but I only have 1 PT1000 now and I would like to have several PT1000. How should I change the code to obtain the measurements of all the sensors on the serial monitor?

You will find the wiring conection I have done and the code on the txt file.

Thank you!
