Merge request for multiple repositories

Hi @everyone Currently, I have set up v15 for my company. In the ‘apps’ folder, there are a lot of apps or modules, and each app has its own repository. Let’s say I made some changes for multiple repositories on my branch. How can I make a pull request to the main branch with a single pull request? It’s not ideal to create pull requests one by one for each repository based on my changes. Can this be resolved if I use git subtree?
