Ignore non-selected channel keyframes during keyframe navigation

I do lots of layout Grease pencil animations where the object itself moves around the scene independent of the drawings occurring within. However, when navigating keyframes back and forward, despite working inside the grease pencil layers, the time slider still stops over the grease pencil OBJECT keyframes. (pictured below, I only want my "go to next keyframe" to pay attention to the grease pencil layer I have selected. Not Frame 50 and such)

! The request: ! Unless I'm missing something, it'd be great to have "goto next keyframe" and such only pay attention to a selected channel (unless nothing is selected obviously)

This isn't solely limited to grease pencil obviously. Similar functionality in the Graph editor would also be spectacular.
