Git: Interactively rebase a range of commits

I'm trying to rebase -i a few commits that occurred a while back in my history. Say I have a log like this:

* 5e32fb0 (HEAD -> master) Add latest feature
* 106c31a Add new feature
* 2bdac33 Add great feature
...100 other commits...
* 64bd9e7 Add test 3
* 3e1066e Add test 2
* 26c612d Add test 1
* 694bdda Initialize repo

and I want to squash the 3 test commits. In these circumstances, git rebase -i HEAD~106 isn't very practical. What I'm looking for instead is something like git rebase -i 64bd9e7:26c612d.

Does git have this sort of behaviour, and if so, how can I use it?

I had a look at this post, but it didn't answer my question.

In order to squash those three commits, you'll need to re-write history for the entire repository. That is, all the commit hashes for commits after those test commits will be modified. The most straight-forward way to do it, in my opinion, is to:

1. Create a temporary branch and checkout pointing at 64bd9e7.
2. Squash the three commits together.
3. Checkout your main branch, and reset it to the commit immediately after 64bd9e7.
4. Rebase it onto your temporary branch
