Support for a series of patches, i.e. patchset or changeset?

Hi All,

Does anyone know if git has sort of support for a series of patches, i.e. a patchset or changeset? So whenever we know the SHA1 id of a single patch/commit, we know the patchset it belongs to. This is normal when we do big changes and split that into smaller pieces and doing only one simple thing in a single commit.

This will be especially useful when tracking and cherry-picking changes, i.e. monitoring on the changes of some specific files, and if a specific patch is interesting, we may want to apply the whole changeset, not only that specific one.

Ideas?
