Pin a Channel (bone) in the Dope sheet

In the Graph Editor, you can pin a channel so it stays in channel region even when you click off of it. Very Useful. If this could be added in the Dope sheet/Action Editor that would be amazing. Example: I want to pin the bone "hand_ik.R" in the dope sheet, then select the bone "shoulder.R", but still be able to see where I have keyframes on the hand, without switching back and forth and still have "Show selected" checked. Thanks!
