Collapse Stash commits in log window into a single "summary" representation

Currently, each git stash shows up as a connected set of multiple sub-commits.

This is annoying because, when trying to see what files are part of a stash, you've got to click around to all 3 commits to see all the files.

What I would like is a way to collapse all three (visually, in the log) to a single line item that summaries the contents of all 3 commits, so I only need to look in one place.
