Lock Marker on timeline to keep from accidentally clicking on it and moving it.

I have markers with durations that I’d like to keep locked on the timeline to avoid grabbing and moving them. I’m not talking about the ripple sequence markers option. I mean, as if you were locking a track.

The markers are so close to where you would click to drag the playhead that I sometimes grab them and have to undo. As you can see from the screenshot, when you have a lot of layers, the room you have to move the playhead is minimal.

The only workaround I can think of is to create null clip and copy them all to that clip, then lock that track.
