Any way to show only properties themselves in Timeline, not their "groups"

mmdestiny

The Timeline hierarchy is extremely cumbersome to navigate when trying to select a property for editing the f-curves or property-level keyframes.  The Properties dropdown is a matryoshka doll of groups.

Say you wish to edit just the Side-Side of the left foot.  Sure, clicking the left foot in the viewport shifts the Timeline focus to the left foot root, but then you still need 6 (!) additional clicks to go Left Foot>Properties>General>Transforms>Rotation>Side-Side.

When the vast majority of animation is probably done to transform properties, this seems a little overkill.

Is there any way to filter out the group nesting of properties in the timeline so that clicking the Properties dropdown of, say, Left Foot, will show only "Bend, Side-Side, Twist, Visible in Render, Cast Shadows" and not all the nested groups?
