How do I use selectionName with GuiService?

AddSelectionTuple and AddSelectionParent take in a selectionName parameter. Is it possible to utilize this? I’ve read through all the docs I could find, but I wasn’t able to find anything such as GuiService:SetSelection(selectionName). Using AddSelectionTuple or AddSelectionParent with a selectionName you have previously used results in this warning:

GuiService:AddSelectionTuple already has selection group with name [selectionName], overwriting selection group.
