There is! You can find the current "agreed upon" human genome reference segmented by chromosome here: https://hgdownload.soe.ucsc.edu/goldenPath/hg38/chromosomes/. (It's not the assembly that's described in the article here.)

People do talk about the genome and its elements using the location by chromosome number and range like you'd describe an index in a string. There has even been special notation developed to do so [1]. However, it depends on _how_ you're looking at biology.

I think an analogy would be: you can describe all code as machine code, but when there are higher level abstractions you wouldn't choose to do so.
