Add Insert or Center Snap to Pressure Objects in Profile Views

[Cadguru42]

Currently there is no ability to snap to the center or insertion point of a pressure fitting or appurtenance in a profile view. Please add that ability. There is already a grip for it when selecting the object, but there isn't a way to snap to that same point.

And give us the ability to use that snap as the anchor point for our labels without having it try to hold leaders off of the fitting/appurtenance.
