Using git rebase, how to squash a commit into a non-previous commit

I know that using git rebase -i, I could squash a commit which will meld the commit message into the immediate previous commit.

But using git rebase -i, is it possible to squash a commit into not the previous commit but a commit even older? Lets say I want to squash a commit with a commit that is 3 commits prior to the commit being squashed. If yes, then how?

Solution

when you use git rebase -i you are able to reorder the commit if you want to a new order.

If you e.g. do git rebase -i HEAD~5 and end with this:

  pick bfddbf6 first  commit
  pick 74b19b1 second commit
  pick 03892e7 third  commit
> pick 0fdc12c fourth commit
  pick 9e422a0 fifth  commit

you can reorder the fifth commit as second to squash it into the first:

  pick bfddbf6 first  commit
> squash 0fdc12c fourth commit
  pick 74b19b1 second commit
  pick 03892e7 third  commit
  pick 9e422a0 fifth  commit
