Perhaps you would like one of the monorepo management tools like Lerna?
In general, the best advice is to avoid nested git projects as much as possible (even though tools like git submodules exist, they are more footguns than you want them to be). You either want to reorganize your folder tree so that your git projects are only ever side-by-side rather than nested, or that there is only one repo for all of them ("monorepo"), depending on your preferences and when/how you expect to share them.
