Automatically grant access to sub-albums

When albums are arranged in a hierarchy it would be nice to be able to grant access to all sub-albums when granting access to a higher level album. For example, in the following structure:
Album1
Album1A
Album1Aa
Album1B
Album2

I would like to grant access to Album1, Album1a and Album1b in one shot. I can think of two ways to accomplish this:

1. On the Add/Edit Group page, add another column beside "Access Level" and "Writable" with a checkbox to control this behaviour.
2. In config_inc.php have a variable that would turn this behaviour on globally

At the same time there should be the ability to override this behaviour for specific albums. In the example above, I could override access to Album1Aa if I wanted to.
