If you want concentric deforming hexagons…this could be a start.

If there is a group already defined on the incoming of the wrangle and you specify the name of that group in the parameter you are speaking of;

That group will become highlighted as a group selection in both the geometry spreadsheet and in the viewport.

This can be handy as a visual aid for other operations.

P.S. Thanks for asking this question, otherwise I did not know of this option. I have had in the past the need for it, and as an aid wrangled my groups to a specific color to be able to see the group as a visual aid. Now that I know of this option, can do it more quickly.

You mean the warning you get?

using i@class=1 instead removes the warning.

But I have no clue about Tops…so I don't know if this is the issue.
