as far as I understand once you run bench update all existing apps are being updated (I think under the hood through some sort of a git pull or git fetch/merge command).
Let’s say you have many custom apps it could be that there is a situation where you only want to update Frappe/ERPnext but not the custom apps. Is there any way to do so? For example can you just navigate to /apps/erpnext and execute a git pull origin there?
