What you can do though, assuming you want to name multiple objecta the same, is select all of the items to rename in the Hierarchy, then type the name for them into the Inspector, all of the items will be renamed the same.
Aw Rob, my fellow South Westian, you’ve failed me lol. I don’t really want them named the same, I just want the 1,2,3 or A, B, C etc to increment depending on how I’ve named it. I wonder why they changed that??
