2 transmitters with different channel numbers to one RX and to Excel columns

Projects Programming
2

Thus if I summarize it:
First TX_P
<>
radio.openWritingPipe(pipes[1]); // first pipe
radio.setChannel(0x60); //channel 60 for A column
</>

Second TX_C
<>
radio.openWritingPipe(pipes[1]); // first pipe
radio.setChannel(0x58); //channel 58 for B column
</>

How do I separate the columns A and B at RX? and how do I write it?
Thanks
