There is, but it doesn’t.

A .tar.gz archive is (most of the time) a single compressed stream of
a multi-file container.

On the contrary, a zip archive is a container of multiple compressed
file streams. So, in a zip archive, each contained file can be
compressed by a different algorithm. It does not make sense to only
give the user a way to change compression for all files in a zip at
once.
