Chiseled bookshelves Option

I have an idea for chiseled bookshelves, which would be to put an option that can be activated or deactivated so that you can save or grab the books as it is, for example, put the 6 books and your power to grab any not necessarily the last, and this would be an option that the computer has active and while the cell phones do not,  to make it easier and not have to decide between grabbing the last one or grabbing whatever.
