Is there a way to hide rows without deleting them?

I use this to keep track of orders. Once completed, is there a way for me to hide that order but still keep it in my records? I don't want to permanently delete them. Just hide the completed row/ order so it is easier to see what I still need to complete.

All of my completed orders are the starred ones.

Please note that you can filter the display to only show those that were not "starred" which is referred as Unfavored.
