Is `llvm-cov report` only able to take one binary?

I’m looking at this page: https://llvm.org/docs/CommandGuide/llvm-cov.html#llvm-cov-report.
I wonder does PROFILE BIN mean that we can only have one binary for llvm-cov report? Can we provide more than one? Besides, is it also applied to llvm-cov export/show?

Any suggestion would be helpful. Thank you for your help!
