Does JMP label the centroid in a mixture design?

Center points in small design spaces can often be identified in the data table by inspection. This becomes much more difficult for mixture designs with large numbers of components (>=5), especially when linear constraints are superimposed. When design points match classical designations (e.g., vertices, centroids, binary double blends, axial check points, etc.), does JMP have the ability to label those? I am unable to find the centroid by inspection in these larger systems. Thanks in advance.

Have you tried using a Ternary Plot (under Graph Menu) and then selecting the interior point(s) in the design, and then using the Rows > Markers to mark the row(s)?

There is a script in the Sample Scripts folder of JMP called LabelMixturePoints.JSL. This script will identify vertices, edges points, etc. It will not label a centroid, instead it will state that the point is an Interior point.
