[PotteryBarn] Add snapping points to some native assets

[ST-DDT]

It would be cool if some of the native dvergr/black marble build pieces had snapping points.
Would it be possible to add them to the existing assets?
The assets should be visible without any mods as they are right now, but with the mod installed, you get the additional snapping points.

These pieces are almost entirely useless without functional snaps.

...assuming its possible at the mod level...
A mod dedicated to allowing users to arbitrarily add snaps to any piece would be of significant use to potterybarn as well as other buildpiece mods that have garbage snaps in them, and almost all of the available buildpiece mods suffer from this.
