This simply isn't possible when using submodules with any code review
tool I know of, because submodules do not contain content, only
*pointers* to content elsewhere in another repository.

To accomplish what you want you we would instead need to use 'git
subtree' instead of submodules, which essentially allows multiple git
repositories to live under a unified umbrella. But that comes with
some other problems (the least of which is that 'git subtree' is not
an official Git tool; it is a 'contrib' tool).
