As of now, to achieve the same function as this command....

git -c diff.mnemonicprefix=false -c core.quotepath=false submodule update --init --recursive --remote

.... users will need to open a submodule as a new bookmark, and then interact with the submodule independently, e.g pull updates. This will update the reference in the parent project in which users can then commit through the parent bookmark.

It will be nice if there's a button or a checkbox to perform this immediately.
