The only way I know on how to add an item to the bottom of a group is to delete the group header and then recreating the group while including the new item. I am wondering if there is a way to add an item to the bottom of a group without deleting the group header?
OK that's a trick that never crossed my mind, much better than deleting and recreating the group, thanks!
I must be missing something, does this not do what you need?
You can also copy paste, insert, etc. but if you want the item/product as the last item in the group then as far as I can tell, you are out of luck, you need to delete the group header and re-create the group and don't forget to copy the group's header text before you do it otherwise you are back to re-creating that too.
You can drag items into a group, have you tried that?
