feature request. single file kernel output download from cli

Using the cli, it could be great to download only:
- the kernel output log
- a single file: i.e. history.csv
without the need of downloading all the kernel output

In my case, I'd like to download all my kernel outputs to my computer, to merge them and analyze them at a glance. But I'm saving large checkpoints that I didn't like to download.

It could be even better if we could list the kernel output files
