Rename a Submodule containing folder

[Thomas]

Scenario: I have a project with submodules inside a theme folder. I'd like to copy the entire project as a new project and change the theme folder name. This in turn would require the submodule path created in Sourcetree to be updated. I assumed/hoped I would only need to update submodule path manually in two places. (1) - the root .gitmodules file as well as (2) - the .git file located within the linked submodule folder.

.gitmodules file example (1):
[submodule "wp-content/themes/[CHANGE-THIS-NAME]/dev/vendor/aria-navigation"]
path = wp-content/themes/[CHANGE-THIS-NAME]/dev/vendor/aria-navigation
url = https://github.com/proteusthemes/WAI-ARIA-Walker_Nav_Menu.git

.git file example (2):
gitdir: ../../../../../../.git/modules/wp-content/themes/[CHANGE-THIS-NAME]/dev/vendor/aria-navigation

While I'm sure these changes are necessary, it does not update the submodules section on the left bar of Sourcetree. It remove the submodules section all together as if it does not recognize they are exist.

My question: Is there a way to rename the containing folder for submodules that sourcetree will recognize?
