Freeze animation - parent to self

This would be a toggle where you could effectively freeze the keyframes and allow you to move the layer as if it were a null to itself. I know I can select all the keyframes and set the current time to a frame where one keyframe is and them move my object and all the keyrames will adjust relatively. But this can be tedious, expesicall if the keyrame you want isn't on the current frame you're trying to adjust. And yes, I can create a Null, or precomp etc, but sometimes this is a hassle. Sometimes you might have dozens or hundreds of animated objects and it woudl be really handy and a time saver to toggle a switch or a key command to allow the reposition of a layer and move the keyframes regardless of what frame I'm on and without having to select keyframes. I can create a null attach, move and delete the null, it's just a lot of steps. Thanks for listening!
