Want project locking for After Effects like Premiere has

Have been wanting this feature for a long time, it's been great for Premiere, and would love to see the same implementation in After Effects. We don't need to be able to collaborate in Ae in my office, but we often pass projects around, and this would save a lot of time hunting down people to make sure no one has the project open and we don't write over each other's work if we need to jump in and change a lower 3rd or something.
