Multi-channel file into multiple tracks

Hello,

please excuse if this has been answered somewhere else already; I did not find it.

Is there a way to put the channels (in my case: 4 to 5) of a single broadcast wave source file

into seperate tracks of a multitrack project

without splitting them up into mono files first?

(It just seems inelegant to me, because it would mean doubling my amount of source files.)

Thanks so much in advance!
