Customer Request: Access full source of old commit in BitBucket

We have need of our QA team to be able to see what version of our software specific PR's was merged into. We can not find any functionality in BitBucket that will let us do this.
Essentially we need to be able to look at the commit for a PR, and then see the full source that the repo had for that commit. (meaning every single file within that commit.)

We found a workaround with doctoring URLs in this article here but for our QA team this is not ideal.

If this is not possible please consider this a feature request.
