Nver mind. I found out that, either right clicking and selecting lock option OR clicking the lock on layers panel locks the parent and child elements, but using a short cut, CTRL+Shift+L locks only the element selected. This feature is already available, but it was not evident or clear to begin with. Is there a way to make it more evident / discoverable and clear for the users. Like for example, right clicking shows both Lock parent and child and also lock selected. Add a shortcut key for locking all similar to locking the selected elements.
