[SS10] Array along path into Graphic Group?

I need to place a lot of barrels in a construction zone. The Array Along Path tool is great for this, however, it would be nice if all the barrels along any one path could be saved into their own Graphic Group.

I'll admit, I am woefully ignorant of Graphic Group usage. I was scared away from them after some disastrous unanticipated consequences early in my career. I'm still leery of them because there is no visual clue when an element is a member of a GG, but I will admit there are times that it is nice to have elements treated as one large group instead of just a bunch of single elements. Due to my ignorance, I am unsure of the ways to create GGs, or if there is a way to do so somewhat automatically.

The other option that would be nice, if it is possible, would be to make my array Associative to my path. I don't see that option in the tool settings, so I assume it's not possible...But could I be wrong?

I am using MicroStation and/or Power Geopak SS10. Thank you.
