Does anyone know how the position of a prop, can be entered into a Library. as a preset?

I've a set of Flowers, that go into V3's hair.  For frontal renders they look good in one place, but for quarter turned shots they look better in another.

I tried saving a pose, for the prop, in hopes that this would also record the X, Y, and Z Transitions; but apparently not(no Hip(?).

My solution was just to load a couple sets of the prop, and toggle Visibility On/Off; but I've found yet another position I'd like to keep them in, so this is wearing thin.

I think I may be interested in converting the Prop to a Figure, but have never done this?

Else, I've heard of Smart Props, but have never made on of those either?
